Baby Eczema: An Australian Parent's Guide

A red, dry patch on your baby's cheek. A scratchy little hand reaching back to rub it. A rough night, then another. If that's where you are right now, you're not alone, and you haven't done anything wrong.

Eczema, or atopic dermatitis if you want the clinical name, is one of the most common skin conditions in Australian babies. Australian data put the figure at up to around a third of children. Most cases start before a baby's first birthday. It runs in families, it flares and settles, and it usually improves a great deal by the time a child reaches preschool age.

When a baby first shows eczema, parents often go down a rabbit hole of conflicting online advice and end up more anxious than informed. The Australian clinical position is actually quite clear. Get the everyday skin care right, know what flares look like and what to do about them, sort out a few obvious triggers, and have a written plan from your GP for when things get worse. Done well, that approach handles most childhood eczema.

This guide is the place to start. It's written for a parent reading on a phone with a baby on their hip, not for a textbook. None of it is medical advice for your baby specifically. That part is the job of your GP and your maternal and child health nurse.

What baby eczema is (and isn't)

Baby eczema, also called atopic dermatitis, is a common long-term skin condition that leaves a baby's skin dry, red, itchy and sometimes weeping. It comes and goes in flares. It is not contagious, it is not caused by poor hygiene, and it is not directly caused by food. It usually starts in the first six to twelve months and improves over the years that follow.

Underneath all that, two things are happening at once. The baby's skin barrier doesn't hold moisture as well as it should, so water leaks out and irritants get in. At the same time, the immune system in the skin reacts more strongly than it needs to. Both come from a mix of genes and environment.

The Eczema Association of Australasia and other Australian clinical sources describe it as a combination of those two problems: an altered skin protein called filaggrin that struggles to hold moisture, and skin that is more sensitive to everyday irritants. That sensitivity then drives the inflammation parents see as redness and itch.

What baby eczema is NOT matters just as much, because the misconceptions cause a lot of grief:

• Not contagious. You can't catch it, and other children can't catch it from your baby.
• Not caused by poor hygiene. If anything, washing too much can make it worse.
• Not directly caused by food. ASCIA is very clear on this point: food allergy does not cause eczema. Food allergy can sometimes trigger a flare in a baby who already has eczema, but it is not the underlying cause.
• Not caused by something you did or didn't do during pregnancy.

The clinical name, atopic dermatitis, sits inside a wider family of conditions called atopic conditions: eczema, asthma, hay fever, food allergy. Babies who get eczema have a slightly higher chance of developing one or more of the others later. That's a pattern, not a destiny. Plenty of children with infant eczema never develop asthma or food allergies.

Why eczema shows up in the first months

Most parents notice eczema between two and six months of age. That timing tracks with how a baby's skin develops over the first few months of life. A newborn's skin is not a finished product. It is still building its barrier function, and in a baby with the genetic setup for eczema, the barrier never quite catches up the way it does for other babies.

The biggest single risk factor for any individual baby is family history. RCH puts this plainly. If you, or another close family member, has eczema, asthma or hay fever, it is more likely your baby will get eczema too. There is a name for this genetic tendency: atopy, and atopy runs in families.

That family-history piece is worth sitting with for a moment. A lot of parents arrive at this point feeling guilty. Did I do something during pregnancy? Should I have eaten differently? Should I have used a different soap? The answer to all three is almost always no.

Eczema is a genetic susceptibility. It is not a parenting failure.

The next thing to know is what doctors think actually triggers a flare on top of that genetic setup. The list is short and consistent across the Australian sources:

• Heat and sweat. RCH names heat as the most common eczema trigger.
• Dry skin. Loss of moisture starts the whole cycle off.
• Irritants. Soaps, fragranced products, scratchy fabrics, dribbled saliva, dribbled food.
• Aeroallergens. House dust mite, pet dander, and pollen for some babies.
• Infection. Common viruses, and certain bacteria on the skin, can trigger or worsen flares.

Notice what's not on that list. Cot type. Brand of nappy. Specific bath product. Most baby eczema is driven by the basics, not by exotic causes. That's good news for parents, because the basics are within reach.

How to tell if it's eczema or something else

Not every rash on a baby is eczema. The first six to twelve months see a parade of skin changes that come and go, and they can look surprisingly similar at a glance.

Eczema in babies under 18 months tends to show up on the cheeks first, then the forehead, scalp, and the outsides of the arms and legs. The nappy area is usually spared because it stays moist. The rash is dry, itchy and a bit rough to the touch.

A few common lookalikes are worth knowing:

• Cradle cap (seborrhoeic dermatitis). Yellowish, greasy scale on the scalp, sometimes the eyebrows or behind the ears. Most often appears in the first three months. The big tell is that cradle cap is usually not itchy. It usually clears up on its own within a few months. See a doctor the same day if it weeps, oozes or smells. If your baby is feeding poorly, drowsy, floppy or hard to wake, call 000 or go to the emergency department. If your baby is under three months old and has a fever of 38°C or more, go to the emergency department now, whatever their scalp looks like. See your GP or maternal and child health nurse if it is no better after two weeks of gentle care, is still there after your baby is three months old, is itchy, spreads to the face or body, or you're not sure it is cradle cap.
• Nappy rash. Confined to the bottom and the area the nappy covers, and often sparing the deep skin folds. Tends to flare with longer stretches between changes, or after a bout of diarrhoea. Blisters in the nappy area of a baby under three months need the emergency department straight away. If your baby has eczema, a cluster of small blisters or punched-out sores needs the emergency department straight away at any age. Honey-coloured crusts, pus or weeping need a GP today. A rash that isn't better after a week of good care is worth a GP visit. There is a separate guide for this on littlepuggles.com.au: see nappy rash or eczema, how to tell the difference for a side-by-side comparison.
• Heat rash (miliaria). Small, raised pink or clear bumps, usually on the back of the neck, the chest, or the skin folds. Comes on quickly when a baby gets hot and settles within two to three days once they cool down. Not itchy in the way eczema is. If your baby has a fever, press a glass on any spots and follow the fever rows under When to get help below: under three months, a fever means the emergency department now, and from three months, see a doctor as soon as possible. Pus-filled lumps or spreading redness need a GP today. Limpness, very few wet nappies or sunken eyes in a hot baby: call 000.
• Milia. Tiny white bumps on a newborn's nose, cheeks or chin. They look like little pearls under the skin. They are not eczema, not infected, and they go away on their own. If you notice a coloured rash or crusting around the spots, see your GP. Pus or spreading redness needs a doctor the same day. If your baby has a fever or seems unwell, follow the fever and red-flag rows under When to get help below.
• Erythema toxicum. Blotchy red patches with small white or yellow centres on a newborn's body. It looks alarming and is harmless in a well baby. It usually appears in the first few days, spares the palms and soles, and clears within about two weeks. 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. If your baby has a fever or seems unwell, follow the fever and red-flag rows under When to get help below. A new rash that first appears after two weeks is worth a GP visit the same day.

A quick note on skin tone. Eczema can look pink or red on lighter skin. On darker skin, the redness can be hard to see. The signs you're looking for are dryness, scaliness, thickening of the skin where it has been scratched, and sometimes patches that look grey, purple or darker brown. After a flare settles, you may see lighter or darker patches that fade slowly. None of that means the eczema is worse, only that it's showing up differently. RCH and DermNet NZ both note this.

Everyday triggers parents can spot at home

The most useful thing you can do in the first month or two of suspected eczema is keep a simple diary. Date, time, what the skin did, and what was different that day. Within a few weeks, patterns usually emerge.

The most common everyday triggers in Australian homes are these:

• Heat. Indoor heating in winter, summer humidity, an overdressed baby. RCH suggests keeping the home below 20°C during the day and the bedroom no warmer than 15°C overnight, with one or two thin layers of cotton. Check your baby's back or tummy, not their hands and feet. 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. Cold hands and feet in a baby who is pale, blotchy, drowsy, breathing fast or off their feeds are a different signal: call 000. If your baby is under one month old and their back or tummy feels cold, call 000, even if they seem otherwise well. From one to three months, follow the low-temperature rows under When to get help below.
• Dry skin. This one is constant. Skin that is not moisturised every day flares more often. The phrase doctors use is that you are managing dry skin even when the skin looks fine. Plain emollient, top to toe, twice a day, every day.
• Fragrance and detergents. Soap, bubble bath, shampoo, fabric softener and fragranced laundry powder are all worth ruling out. Switch to fragrance-free products and run an extra rinse cycle on the washing machine.
• Fabric. One hundred per cent cotton, loose fitting. Avoid wool, and avoid synthetic fabrics that don't breathe. Take the tags off. Sheepskin underlays sound like a good idea but tend to hold heat against the skin.
• Saliva and food residue. Once a baby starts dribbling, the area around the mouth can get inflamed. A pea-sized blob of plain barrier ointment around the mouth before feeds, then a soft wipe and moisturiser after, helps a lot. The same applies after meals once solids start.
• Wipes that contain irritants. Some wipes contain alcohol, benzalkonium chloride, or preservatives like methylisothiazolinone (MI/MCI). All of these can sting and inflame skin that is already sensitive. Read the ingredient panel, and if the ingredients are not listed, ring the manufacturer.
• Older-baby food triggers. Once your baby starts solids, around six months, food can occasionally trigger a flare in a baby who already has eczema. ASCIA is firm that food allergy does not cause the eczema itself. If you suspect a food trigger, see a GP or a clinical immunology specialist before changing your baby's diet.

The skin-safety chain is the cumulative effect of all these small choices. No single one is the silver bullet. The combination is what works.

The basic management approach (what most parents need)

The Australian clinical position on managing baby eczema is settled and consistent. ASCIA, RCH, the Australasian College of Dermatologists and the EAA all describe the same approach. It rests on four pillars:

• Everyday skin care, regardless of how the skin looks today.
• Prompt management of flares with the medication your GP prescribes.
• Trigger awareness and reasonable avoidance.
• A written eczema action plan from your GP, so you know what to do, when, and with what.

Most baby eczema responds to that approach, applied properly, over time. Here are the everyday parts:

• Moisturiser, every day. Use a thick, plain, fragrance-free moisturising cream. Apply it top to toe at least twice a day, every day, even when the skin looks fine, and apply more after a bath or any time the skin feels dry. RCH advises a high-oil, low-water cream and tells parents to avoid moisturisers that contain fragrance, alcohol, sodium lauryl sulfate, or plant or food oils such as olive, coconut, or nut oils. The RCH eczema guideline notes that olive oil may disrupt the skin barrier and sensitise the skin. Aqueous cream BP, a familiar pharmacy product, was originally a wash and should not be used as a leave-on moisturiser.
• Bath routine. A short, lukewarm bath once a day is usually fine and often helps. RCH parent guidance is to bathe in a cool bath no hotter than 30°C, use a soap-free cleanser, and pat dry, then apply moisturiser straight away while the skin is still slightly damp. Soap, bubble bath and shampoo are out during a flare. A capful of plain, fragrance-free bath oil can be added, but bath oils make the bath slippery, so direct supervision becomes non-negotiable.
• Steroid creams during flares. This is the part many parents worry about. The RCH Clinical Practice Guideline is direct: topical steroids are essential to the management of eczema flares, and when used as prescribed they are very unlikely to cause skin thinning or the other issues people fear. The Australasian College of Dermatologists takes the same position. The most common mistake is stopping the prescribed steroid as soon as the redness settles, and then the flare comes back. Use the steroid for as long as your GP has prescribed it.
• Fabric and the nappy area. Cotton, loose fit, fragrance-free detergent, double rinse. In the nappy area during a flare, change frequently and apply a barrier cream at each change.
• Things not to do. Do not put your baby on a restrictive diet to manage eczema unless a specialist has told you to. Do not use perfumed or antibacterial cleansers. And do not stop the prescribed steroid as soon as the redness settles, even if the skin looks better on top.

That's most of it. Done consistently, this approach covers most cases of baby eczema.

When to get help: 000, hospital or GP

Most parents end up at a GP once eczema is suspected, and that's the right place to be. A GP can confirm it's eczema, prescribe the right strength of moisturiser and steroid for your baby, and write up an eczema action plan. RCH includes the maternal and child health nurse on the same list of people who can help with the basics, and the MCHN is a good first stop too.

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.

Call 000 or go straight to the emergency department

• Your baby is floppy, drowsy or hard to wake, not feeding, or otherwise very unwell.
• Your baby is having trouble breathing, is grunting, or has pauses in their breathing.
• Blue or grey lips, tongue or face, or skin on your baby's body that looks pale, blotchy, grey or blue. Don't wait to see whether warming helps. On darker skin the change can look grey or white, so check the lips, tongue and nail beds.
• A seizure.
• A fever with drowsiness, trouble breathing, a stiff neck, a seizure, blue or very pale skin, or a rash that doesn't fade when pressed.
• A rash that doesn't fade when you press the side of a clear glass against it, and it is spreading or looks like purple bruises, or your baby has a fever or seems unwell.
• Your baby is under one month old and their back or tummy feels cold, or their temperature is below 36.5°C taken under the arm, even if they seem otherwise well.
• Your baby is one to three months old and their back or tummy feels cold, their hands or feet are cold, or their temperature is below 36.5°C under the arm, and they also have any other sign on this list, are quieter than usual, have fewer wet nappies, are irritable and can't be comforted, or have a weak, high-pitched or unusual cry. Babies with sepsis do not always have a fever.
• You feel something is seriously wrong.

Go to the emergency department now

Fever in a young baby goes by age, not by how the skin looks. A temperature of 38°C or more, taken under the arm with a digital thermometer, counts as a fever.

• A fever of 38°C or higher in a 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 doesn't fade when you press the side of a clear glass against it, in a baby under three months, even with no fever.
• If your baby has eczema and gets a cluster of small blisters or punched-out sores, especially with a fever, go to the emergency department straight away. This can be a serious herpes-virus infection of eczema-affected skin called eczema herpeticum. Do not wait for a GP appointment. If your baby is floppy, drowsy, hard to wake or seems very unwell, call 000. Don't let anyone with a cold sore kiss your baby.
• Rapidly spreading red areas with fever (possible cellulitis or systemic infection).
• Any skin infection, blisters or sores close to the eye.
• Severe widespread flare in a baby under three months old.
• Your baby is one to three months old and seems their usual self, but their temperature is still below 36.5°C under the arm after you have checked they are not underdressed, warmed them with skin-to-skin contact or an extra layer, and taken it again within the hour. Don't wait out the hour if you are worried or anything changes: go now.

See a doctor as soon as possible

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

• Your baby is three months or older, has a fever and worsening eczema, but is otherwise still well. Under three months, a fever means the emergency department now.
• Your baby is unsettled, feeding poorly or not sleeping because of the itch, but is otherwise alert and responsive. A baby who is not feeding at all, or is drowsy, floppy or hard to wake, belongs in the 000 list above.
• A rash that doesn't fade when you press the side of a clear glass against it, in a baby three months or older who has no fever and seems well. Under three months, it means the emergency department now.

See a GP today

• The skin is weeping, crusted, or has spreading red patches with pus, suggesting bacterial infection.

Book a GP visit this week

• This is the first time you've seen what looks like eczema and you want a clear diagnosis.
• A flare isn't responding to the routine that has worked before.
• You need a prescription, or a repeat, for a topical corticosteroid.

When you see your GP, three things are worth bringing along. A short timeline of when the rash started and what you've tried. A list of any prescription or pharmacy products already used, including how often and how much. And a photo or two of the worst of the flare on your phone, which is gold if the flare has settled by the time you arrive.

If you're not sure where the rash sits between mild and serious, ring healthdirect on 1800 022 222. Nurses are on the line 24 hours a day, and they can help you decide whether your baby needs a GP this week, a doctor as soon as possible, or the emergency department. If your baby seems very unwell, don't wait for the call: ring 000.

Living with baby eczema

Once a routine is settled, baby eczema becomes much more manageable. The day-to-day work is consistent, but it isn't dramatic. Most of the heavy lifting is done by the moisturiser tub, the laundry powder, the room temperature, and the eczema action plan stuck on the fridge.

A few practical observations:

• Track what works. A simple note on the phone, or a sticky-note tally of flares and what coincided with them. Heat. New detergent. Teething week. Within a few weeks, you'll see your baby's pattern, and that pattern is more useful to your GP than any allergy panel.
• Pin the routine to existing routines. Moisturiser after the morning nappy change. Moisturiser after the bath. Most parents find that pinning the moisturiser steps to things they already do daily is the difference between sticking with it and forgetting.
• Keep the medication handy. When a flare starts, action in the first 24 hours is often the difference between a short flare and a long one. Keeping the prescribed cream in the same drawer as the moisturiser saves time when the skin starts to look angry.
• Don't blame yourself. Most parents who arrive at a paediatrician with severe eczema haven't done anything wrong. They've often been doing too much, switching products too often, or stopping the prescribed steroid as soon as the redness settles. Eczema rewards a steady, boring routine more than it rewards effort.
• Know the support is there. The Eczema Association of Australasia (EAA) is the Australian peak body for eczema. They run a helpline, publish parent resources, and host an annual Eczema Awareness Week. If your baby's eczema is making you feel overwhelmed, EAA's parent forum is worth knowing about.

Frequently asked questions

What does baby eczema look like in the first few months?

In babies under 18 months, eczema usually shows up first as dry, red patches on the cheeks and forehead, often spreading to the scalp, the trunk, and the outsides of the arms and legs. The rash is itchy, dry to the touch, and comes and goes. The nappy area is usually spared. On darker skin, redness can be hard to see, so the patches may look grey, purple or darker brown, with dryness and thickened skin more noticeable than colour change.

What causes baby eczema?

Baby eczema comes from a mix of inherited factors and environmental ones. The skin barrier doesn't hold moisture as well as it should, and the skin's immune response is more reactive than usual. Family history is the biggest single risk factor: if a parent or sibling has eczema, asthma or hay fever, your baby is more likely to develop eczema too. Triggers like heat, dry air, fragrances and irritants then drive the flare-and-settle pattern on top of that genetic setup.

When does baby eczema usually start, and does it go away?

Most cases start in the first six to twelve months of a baby's life, with two to six months being typical. Australian clinical sources note that infantile eczema usually improves a great deal between the ages of two and five years, and many children grow out of it altogether. Some children carry it into adolescence or adulthood. Even when it persists, the management approach stays the same.

Is baby eczema caused by food allergies?

No. Food allergy does not cause eczema, according to ASCIA. Babies with eczema are at slightly higher risk of also developing food allergy, but the eczema isn't caused by what your baby is eating, and cutting foods out of an infant's diet without medical guidance can do more harm than good. Speak to a GP or clinical immunology specialist before any elimination diet.

When should I take my baby to the GP for eczema?

Book in with your GP if this is the first time you've seen suspected eczema, if a flare isn't responding to the routine that has worked before, or if you need a prescription or repeat. See a doctor the same day if the skin is weeping, crusted or spreading with possible infection, or if your baby is three months or older and has a fever and worsening eczema. A fever of 38°C or higher, or a rash that doesn't fade when pressed, in a baby under three months means going to the emergency department now, even if they seem well. Go to the emergency department straight away for clustered blisters or punched-out sores, rapidly spreading redness with fever, infection near the eye, or a severe widespread flare under three months. Call 000 if your baby is floppy, drowsy or hard to wake, struggling to breathe, looks pale, blotchy, grey or blue, or has a rash that doesn't fade when pressed along with a fever or seeming unwell. If you're not sure which applies, treat it as the more urgent one.
