Newborn Skin Care: The First Six Weeks

By the time your baby is three weeks old, their skin will have done a fair bit of changing. Most of it is normal. The bits that aren't are usually obvious if you know what you're looking at.

You'll be tired, and you'll second-guess yourself. That's normal too. Newborn skin care gets talked about as if it needs a long list of products and a complicated routine, and for most babies it doesn't.

What works for most newborns is simple: a bath two or three times a week, plain water or a mild wash, pat dry, watch the skin, and don't fuss with it. This guide is the longer version of that. What newborn skin is doing in the first weeks, the routine, what to use and what to skip, clothing and laundry, the nappy area, what's normal, and the signs that mean calling 000, going to the emergency department, or seeing your GP or maternal and child health nurse (MCHN).

What newborn skin is actually doing

Newborn skin care in the first six weeks comes down to four things: short, infrequent baths, plain or mild fragrance-free products, careful nappy-area changes, and watching the skin without trying to fix every change. The barrier is still developing, so less is usually better than more.

A newborn's skin is still adjusting. The barrier function (the part of the skin that keeps water in and irritants out) is still building. Until it does, the skin is more permeable than adult skin. Things that go on the surface pass through more easily than they will later in life.

Vernix is the white-cream coating some babies are born with. It is not dirt, and the current Australian and WHO position is to leave it on. It supports skin hydration, has antimicrobial peptides built into it, and helps the skin acidify in the right direction.

WHO recommends delaying the first bath for at least 24 hours after birth where possible, partly to support vernix. Skin pH shifts in the first weeks too, settling into the slightly acidic range that suits the skin's resident microbes. Frequent washing with anything other than water can disrupt this, which is one of the reasons less-is-more is the Australian consensus position.

In the first one to two weeks, many babies peel. Hands and feet first, sometimes the trunk. Babies born past their due date peel more than babies born early or on time, because they have shed more vernix in utero. The peeling is normal and resolves on its own.

What this means for you, day to day: the skin you can see is doing real work under the surface. It does not need much help.

A simple newborn skin care routine that works for most babies

A simple newborn skin care routine has five core principles: bathe two or three times a week in warm water, use plain water or a mild soap-free wash, pat dry, do nappy changes thoroughly, and only moisturise if the skin is dry. This is the Australian consensus position and it works for most healthy term babies.

How to care for newborn skin: a five-step routine

• Bathe two to three times a week. Daily is fine if everyone enjoys it; more often than that can dry the skin out. Raising Children Network is the source on the two-to-three rule.

• Keep the bathwater between 37 and 38 degrees Celsius. Test with the inside of your wrist or elbow, or a bath thermometer. Hot water systems installed after 5 August 1998 must deliver water to the bathroom tap at no more than 50 degrees; that figure is a ceiling, not a target.

• Plain water, or a mild soap-free cleanser. No bubble bath. No fragrance. No botanicals. Royal Children's Hospital Melbourne (RCH) guidance is to choose products free from fragrance, botanicals, and antibacterial agents.

• Pat dry, do not rub. Pay attention to the folds: neck, behind the ears, groin, and armpits. Trapped moisture is what starts most early irritation.

• Moisturise at the first sign of dryness. RCH advises applying a thick, non-fragranced moisturiser all over daily at the first sign of dryness, and more often if the skin always seems dry. Thicker creams beat lotions. If there is a strong family history of eczema, asthma, or hay fever, talk to your MCHN or GP about whether routine emollient is worth starting earlier, because practice is evolving on this.

Less is more is not a slogan, it is the actual recommendation. Australian guidance, the WHO, and RCH all land in the same place. The newborn skin barrier is doing its own work. The routine that supports it best is the one that does the least.

The technique itself is straightforward. Gather supplies before you undress baby. Wipe eyelids with cotton wool, inner to outer, a new piece for each eye. Support head and shoulders with one arm and the body with the other, and lower feet first.

Wash neck and body first, nappy area last, front to back. Never leave baby unattended in a bath, not even for a moment.

Cord care is plain water and a dry environment. Do not use antiseptics or alcohol wipes, which delay separation, and fold the nappy down away from the stump; most cords come away in 7 to 14 days. Redness spreading around the stump, swelling, bleeding, pus or a foul smell needs a doctor the same day. A baby under three months with a fever of 38°C or more goes to the emergency department now, and a drowsy or floppy baby needs 000.

Products: what to use, what to skip

The shorter the ingredient list, the better. That is the practical version of the Australian advice.

Generally fine

• Plain water (the default)

• A mild, fragrance-free, soap-free cleanser

• A thick, fragrance-free moisturiser if the skin is dry

• A zinc-based barrier cream for the nappy area if there is any redness

Skip

• Anything with added fragrance or perfume

• Essential oils (lavender, tea tree, eucalyptus, Vicks-style products)

• Botanical extracts and food-derived ingredients (oat, goat milk, nut oils, wheatgerm). ASCIA flags these on babies at risk of food allergy.

• Antibacterial washes

• Bubble bath

• Adult skincare, including adult acne products with benzoyl peroxide, salicylic acid, or retinoids

• Baby powder and talc (respiratory risk)

• Aqueous cream that contains sodium lauryl sulfate (irritant)

There is a pattern in that list. You'll see most of those products lined up on the baby aisle at the chemist, and most of them solve a problem newborn skin doesn't have. The barrier is building. Don't load it up.

For wipes, look for fragrance-free, alcohol-free, and short ingredient lists. Plain water and a soft cloth still does a perfectly good job in the early weeks if that is easier for you.

Clothing, fabric, and laundry

100% cotton is the workhorse here. It breathes, it washes well, and it handles being in contact with skin all day without trapping heat.

Wash all new clothes, sheets, and wraps before they touch the baby. The starches and finishes used in manufacturing are not designed to sit against newborn skin.

Use a fragrance-free detergent. Skip fabric softener. It leaves a residue that can irritate, and on cotton it actually reduces breathability.

Cut tags out if they sit against the skin. Watch the seams of bodysuits at the neckline and on the inside of the legs. Rough seams cause more skin reactions than most people expect.

In the first weeks, layering matters more than thickness. A cotton bodysuit and a lightweight wrap or sleeping bag matched to the room temperature is usually enough. Cool hands and feet are normal when your baby's tummy feels warm, their lips and tongue are pink and they are settled and feeding well, so check the tummy rather than the hands before adding layers. Cold hands and feet in a baby who is pale, blotchy, drowsy, breathing fast or off their feeds are a different signal: call 000.

Babies with sensitive skin can react to more of the above, so keeping the ingredient list short matters even more for them.

Nappy area care in the first weeks

Most nappy-area irritation in the first six weeks comes from prolonged contact with wee or poo, not from the nappy itself. The fix is the same in any era: change often.

The four basics

• Six or more changes a day in the early weeks, and as soon as the nappy is soiled.

• Plain water on a soft cloth or cotton wool, or fragrance-free, alcohol-free wipes.

• Front to back for girls. Do not retract the foreskin in uncircumcised boys.

• A thick layer of zinc-based barrier cream at each change if redness appears.

Air time helps. A few minutes on a towel between changes is enough.

For babies with very sensitive skin, nappy materials can matter more than they do for other babies. If you are seeing a reaction, your MCHN or GP can help you work out what is triggering it.

A note on size. As baby grows, nappy fit changes. Red marks on the thighs or waist, leaks at the leg cuffs, or a nappy that looks like it is straining at the tabs are usually fit issues, not skin issues.

If a rash in the nappy area appears and is not improving with the four basics over a week, see your GP. There is a separate nappy rash guide if that is what you are dealing with.

Honey-coloured crusts, pus, weeping, bleeding or ulcers, or redness spreading past the nappy line, need a GP today. Blisters in the nappy area of a baby under three months need the emergency department straight away. Any rash with a fever of 38°C or more in a baby under three months means the emergency department now, and a baby who seems unwell with a rash belongs in the 000 list below.

What's normal (and what isn't) in the first six weeks

Newborn skin care in the first six weeks isn't only about the routine. Knowing what's normal, and what isn't, is the bigger half of it. Newborn skin will do a surprising number of things in the first month. Most are normal.

Common, harmless changes

• Milia. Tiny pearly-white bumps on the nose, cheeks, and chin. Around 40 to 50 percent of newborns have them. Do not squeeze, do not apply anything. They clear on their own in weeks to a few months. A coloured rash or crusting around them is worth a GP visit; pus or spreading redness needs a doctor the same day. If your baby has a fever or seems unwell, follow the fever and 000 lists below.

• Erythema toxicum. A blotchy red rash with small white or yellow centres. Looks alarming, does not bother the baby, and comes and goes for the first week or two, usually sparing the palms and soles. Spots that turn into blisters, or a cluster of small fluid-filled spots, are not this rash: in a baby under three months, go to the emergency department straight away. With a fever or a baby who seems unwell, follow the fever and 000 lists below.

• Baby acne. Red pimples on the cheeks, nose, and chin from around two to six weeks. Hormonal, and settles on its own. New pimples that first appear after six weeks are worth a GP visit this week; spots that spread, weep or crust need a doctor the same day. If your baby has a fever or seems unwell, follow the fever and 000 lists below.

• Cradle cap. Yellow, greasy scaly patches on the scalp that are not contagious, are not caused by anything you have done, and usually clear within a few months. To lift the crusts, soften them with a plain, fragrance-free moisturiser overnight, then wash with baby shampoo and lift them with a soft brush. If it weeps, oozes or smells, see a doctor the same day. If your baby is feeding poorly, drowsy, floppy or hard to wake, call 000 or go to the emergency department, and if your baby is under three months with a fever of 38°C or more, go to the emergency department now. See your GP or MCHN if it is no better after two weeks, lasts past three months, is itchy, spreads, or you're not sure it's cradle cap.

• Mottling. A faint, lacy pattern on the arms and legs for a moment when baby is undressed or out of the bath. If it goes as soon as they are dressed and warm, their lips and tongue are pink, their tummy is warm and they are feeding and alert as usual, it is usually a normal newborn change. Blotchy skin that stays once your baby is warm, that covers the tummy, back or face, or that comes with any sign in the 000 list below is not this: call 000, and if you're not sure which it is, call 000.

• Stork bites. Pink-red flat marks on the eyelids, forehead, or nape of the neck. They blanch when pressed and fade over the first year or two. A mark that is darker, thicker, raised or growing, or a mark low on the back with a tuft of hair or a dimple, is worth a GP visit.

• Peeling. Especially on hands and feet. More common in babies born past their due date. Peeling still going after three to four weeks, or dry red patches, is worth a GP visit. Red skin that looks scalded, blisters or peels off in sheets is an emergency, with or without a fever: call 000.

There is a longer pillar piece on each of these in the Newborn Skin Changes guide.

A lot of common advice from older relatives is well-intentioned and out of date. Milia are not milk on the skin. Cradle cap is not a hygiene problem. Stork bites are not bruises.

Dermal melanocytosis (flat blue-grey patches on the lower back or buttocks, more common in babies of African, Asian, Indigenous, or Mediterranean heritage) is not a bruise either, and it should be in baby's personal health record after the first MCHN check. The point of recording it isn't to medicalise the birthmark; it's so a future GP, hospital, or childcare worker doesn't mistake it for a bruise. A mark that appears after birth, changes over a few days or is tender is not a birthmark: see a doctor the same day. Spots or bruising that don't fade under a pressed glass follow the non-blanching rash rows below.

A few specific old chestnuts come up a lot. Bathing in cooled boiled water has been replaced by plain tap water, and Australian tap water is fine for newborn skin. Putting baby in the sun for jaundice is not a treatment and risks overheating; phototherapy in hospital is the actual treatment.

Jaundice, a yellow tinge to the skin or the whites of the eyes, is common from the second or third day and usually fades within two weeks in a baby who is feeding well. Yellowing in the first 24 hours after birth is not this: go to the emergency department, or call your birth hospital, straight away. A jaundiced baby who is sleepy, feeding poorly or having fewer wet nappies needs the emergency department too. A jaundiced baby who is hard to wake, has a high-pitched cry, arches their back, or is stiff or floppy: call 000.

Check the poo as well as the skin. If you see a poo that looks pale, like putty or chalk or pale yellow-white, or the wee is dark, take a photo on your phone and see your GP that same day, or go to your nearest emergency department. Early recognition changes the outcome. Yellowing that spreads to the palms and soles or deepens in the second week needs a doctor the same day, and jaundice still there after two weeks (three weeks in a baby born early) needs a GP visit that day.

Olive oil for cradle cap is out: healthdirect advises against it because it can cause a yeast infection, and a plain, fragrance-free moisturiser softens the crusts instead. Eucalyptus on the chest, lavender in the bath and talc in the nappy area are out too, and several of them are now actively advised against. The Australian guidance is consistent: most normal newborn skin changes clear on their own and need no treatment beyond simple daily care.

What's not normal: blisters, pus, a widespread rash, fever, a baby who's lethargic or feeding poorly, a non-blanching rash (one that does not fade when you press the side of a clear glass against it), or any rapid spread. These move from the watch-and-note category into the call-someone category, and the section on when to get help, further down, says who to call and how fast.

Some need 000 straight away: blue or grey lips, tongue or face; a baby who suddenly turns pale, blue or grey; pale, blotchy, grey or blue skin on the body, without waiting to see whether warming helps; or cold hands and feet in a baby who is also feverish, drowsy, floppy or off their feeds. Healthdirect lists pale, blotchy or blue skin as a reason to call 000, and the Royal Children's Hospital notes that sick babies do not always show a fever. A colour change is not always an infection: it can be the first sign of a heart problem that wasn't picked up at birth, so call 000 even if your baby has no fever.

When to see your GP or MCHN

Most early skin questions have a non-urgent answer, and the right place to start, in Victoria, is your maternal and child health nurse. The exception is any sign in the section below on when to get help, which goes straight to 000, the emergency department or a GP.

Maternal and child health nurse (MCHN)

In Victoria, the MCH service runs ten Key Ages and Stages visits: a home visit shortly after birth, then 2 weeks, 4 weeks, 8 weeks, 4 months, 8 months, 12 months, 18 months, 2 years, and 3.5 years. The early visits are exactly designed for skin questions like these. At the home, two-week, four-week, and eight-week checks, your nurse will look at general skin condition, the umbilical area, jaundice, birthmarks, early signs of eczema or cradle cap, and the feeding and growth context that goes with all of that.

Here's what your MCHN will be checking, in plain terms:

• Skin colour and hydration

• Cord healing

• Any rash, and where it sits

• The state of feeding and growth

• Anything you've spotted since the last visit

They are salaried, free, and they see dozens of new babies a week. They are the right call before Dr Google.

Between visits, the MCH Line in Victoria is 13 22 29, free, 24 hours, staffed by MCH nurses. Other states have equivalent services under different names: Child and Family Health Nurse in NSW, the Child Health Service in Queensland, Community Health Nurse in WA, CaFHS in SA, CHaPS in Tasmania. healthdirect (1800 022 222) is the national nurse advice line and runs 24/7. Tresillian (1300 272 736) and Karitane (1300 227 464) are also useful for broader early-parenting support.

Worth writing down before your MCHN visit

If you're a list person, jot a few notes on your phone before you go. Most MCHNs will ask about all of this anyway; having it written saves the brain power.

• Skin changes since the last visit, and where on the body

• Any rash, plus when it appeared and what it has done since

• Feeding pattern: how often, how long, anything that has worried you

• Sleep pattern: where baby sleeps, how long, how settled

• Anything that has worried you, even if you can't put a finger on what

When to get help: 000, hospital or GP

Some signs need an ambulance or the emergency department straight away. Some need a doctor as soon as possible, and some a GP today. Others are worth a GP visit this week. If you're not sure which group your baby fits, treat it as the more urgent one, and call 000 if your baby seems very unwell.

For babies under three months, use a digital thermometer under the arm. A normal temperature for a young baby is about 36.5°C to 37.5°C.

Call 000 or go straight to the emergency department

• Blue or grey lips, tongue or face, a baby who suddenly turns pale, blue or grey, or skin on your baby's body that looks pale, blotchy, grey or blue. Don't wait to see whether warming helps, and don't wait for other symptoms. In babies with darker skin the change can look grey or white rather than blue, so check the lips, tongue and nail beds.

• Cold hands and feet together with any other change: pale, blotchy or blue skin, drowsiness or floppiness, fast or difficult breathing, poor feeding, a fever, or a baby who just doesn't seem right to you. Hands or feet that stay blue once your baby is warm, after the first day, belong here too.

• A baby under one month who feels cold when you touch their back or tummy, or whose temperature is below 36.5°C under the arm, even if they seem otherwise well. In newborns, a serious infection such as sepsis can cause a low temperature instead of a fever.

• A baby aged one to three months who feels cold on the back or tummy, has cold hands or feet, or has a temperature below 36.5°C under the arm, and has any of these: floppy, drowsy, quieter than usual or hard to wake; not feeding, or fewer wet nappies; irritable and you can't comfort them, or a weak, high-pitched or unusual cry; trouble breathing, grunting or fast breathing; pale, blotchy, blue or grey skin; a rash that doesn't fade when pressed; a seizure; or you feel something is seriously wrong. Babies with sepsis do not always have a fever.

• A fever with any of these: drowsy or hard to wake, trouble breathing, a stiff neck, a seizure, looking blue or very pale, or a rash that does not fade when you press on it

• A rash that does not fade when you press a clear glass against it, if it is spreading or looks like purple bruises, or your baby has a fever of 38°C or more or seems unwell in any way

• Difficulty breathing, grunting, working hard to breathe, or pauses in breathing

• Widespread blistering or peeling, or painful red skin that looks scalded

• Any rash with breathing difficulty or swelling of lips or tongue

• An unwell, drowsy, floppy or hard-to-wake baby, with or without a rash, or a baby with a rash, blisters or cradle cap who is feeding poorly or not feeding

• A jaundiced baby who is hard to wake, has a high-pitched cry, arches their back, or is stiff or floppy

• A seizure, or a feeling that something is seriously wrong

Go to the emergency department now

• A fever of 38°C or higher in any baby under three months, with or without other symptoms, even if they seem otherwise well. healthdirect advises taking a baby under 3 months with a fever to the nearest hospital emergency department immediately. Do not wait for a GP appointment.

• A rash that does not fade when you press the side of a clear drinking glass firmly against it, in a baby under three months, even if they have no fever and seem well. Do not wait for a GP appointment.

• A baby aged one to three months whose temperature is below 36.5°C but who is feeding, settling and behaving as usual. Check they are not underdressed or in a cold room, warm them with skin-to-skin contact or an extra layer, and take their temperature again under the arm within the hour; if it is still below 36.5°C, go to the emergency department. Don't wait out the hour if you are worried or anything changes: go now, and call 000 if any sign in the list above appears.

• Blisters, or a cluster of small fluid-filled spots, on a baby under three months

• Yellow skin or eyes in the first 24 hours after birth (or call your birth hospital straight away), or a jaundiced baby who is sleepy, feeding poorly or having fewer wet nappies (a jaundiced baby who is hard to wake belongs in the 000 list)

See a doctor as soon as possible

This means within hours, the same day, not a routine booking. If no GP can see your baby within hours, go to the emergency department.

• A poo that looks pale, like putty or chalk or pale yellow-white, or dark wee. Take a photo on your phone to show the doctor.

• Jaundice that spreads to the palms and soles, or deepens in the second week

• Redness spreading around the umbilical stump, or a stump that smells or oozes

• Breathing that stays fast even when your baby is resting, getting sweaty or worn out during feeds, feeding poorly, not gaining weight, or puffiness around the eyes, tummy or legs. These can point to a heart problem that wasn't found at birth.

• A mark that appears after birth, changes over a few days or is tender

See a GP today

This means a GP or an after-hours GP today. In Victoria, Nurse-On-Call (1300 60 60 24) can help you work out where to go.

• Cradle cap that is weeping, oozing or smells off (a baby with cradle cap who is feeding poorly, drowsy, floppy or hard to wake belongs in the 000 list)

• Honey-coloured crusts, pus, weeping, bleeding or ulcers in the nappy area

• Pus or spreading redness around spots, or spots that spread, weep or crust

• A new rash that first appears after two weeks of age, even in a well baby

• Jaundice still there after two weeks, or three weeks in a baby born early. Check the colour of the poo too.

Book a GP visit this week

• Nappy rash is not improving after a week of the four basics

• Peeling is still going past three to four weeks

• Cradle cap that is no better after two weeks of home care, is still there after three months, is itchy, has spread to the face or body, or that you're not sure is cradle cap

• New pimples that first appear after six weeks

• A mark that is darker, thicker, raised or growing, or a mark low on the back with a tuft of hair or a dimple

If something doesn't look right and you can't put your finger on what, ring, and if your baby seems very unwell or you feel something is seriously wrong, call 000. Trust your instincts. The whole reason 24/7 services exist is so you don't have to decide alone at 2am. The MCH Line in Victoria, Nurse-On-Call, and healthdirect are all designed for that call.

If you've made it to the end of this guide, you've got the basics. The rest is watching, recording what you see, and asking when you're not sure. Most newborn skin sorts itself out in the first two months. The simple routine is what supports it; the questions you'll have are what your MCHN is for.

Frequently asked questions

How often should I bathe my newborn?

Two or three baths a week is enough to keep most newborns clean, per Raising Children Network. Daily is fine if everyone enjoys it, but more frequent bathing can dry the skin out.

What should I put on my newborn's skin?

For most healthy term babies, not much. Plain water, a mild fragrance-free wash if you want, and a thick fragrance-free moisturiser at the first sign of dryness. RCH guidance is to avoid anything with fragrance, botanicals, or antibacterial agents.

Why is my newborn's skin peeling?

Peeling in the first one to two weeks is normal. It is the skin transitioning from the womb environment, and babies born past their due date peel more. Peeling still going after three to four weeks is worth a GP visit. Red skin that looks scalded, blisters or peels off in sheets is an emergency, with or without a fever: call 000. The full rundown on what's normal in the early weeks is in the Newborn Skin Changes guide.

Is it normal for a newborn to have spots?

Yes. Milia, erythema toxicum, and baby acne are common, harmless and self-limiting, and they look more dramatic than they feel. Spots that turn into blisters, or a cluster of small fluid-filled spots, are not one of these: in a baby under three months, go to the emergency department straight away, and follow the fever and 000 lists above if your baby has a fever or seems unwell. The longer Newborn Skin Changes guide goes through each one.

When should I worry about a rash?

A baby who seems unwell, drowsy, floppy or hard to wake, or who is not feeding, with any rash, needs 000. Blisters, or a cluster of small fluid-filled spots, in a baby under three months need the emergency department straight away. A rash that does not fade when you press a clear glass against it needs the emergency department straight away, even without a fever; call 000 if that rash is spreading, looks like purple bruises, or your baby has a fever or seems unwell. Pus, weeping or a rash that spreads needs a GP today. A fever of 38°C or higher in a baby under 3 months needs to be checked straight away: take your baby to the nearest hospital emergency department now, even if they seem otherwise well.

Can I use sunscreen on a newborn?

For babies under six months, the Australian advice from SunSmart and Cancer Council Australia is shade, clothing, and hats first. Sunscreen is only used on small exposed areas where physical cover is not possible.
