Baby Eczema: Causes, Treatment, and Managing Flare-Ups

Seeing your baby scratching at dry, red patches of skin is distressing. Eczema — also called atopic dermatitis — is one of the most common skin conditions in early childhood, and it often first appears during infancy. The good news is that with the right daily routine, most eczema in babies and toddlers can be kept well controlled. This guide explains what eczema is, why it develops, how to use emollients and steroid creams correctly, what triggers flares, and when to ask for medical help.

What Eczema Is (and What It Is Not)

Eczema is a chronic inflammatory skin condition characterised by a defective skin barrier. The skin of a child with eczema does not retain moisture effectively, which allows irritants and allergens to penetrate more easily and triggers an immune response. That immune response produces itching, redness, and inflammation.

It is not an allergy in itself — but it does belong to what doctors call the atopic march, a pattern in which eczema, food allergy, hay fever, and asthma tend to occur in the same individual, often appearing in roughly that order during childhood. Having eczema does not mean your child has a food allergy, though the two conditions do co-exist more often than in children without eczema.

Eczema is also not contagious. Other children and adults cannot catch it.

How Common Is It?

Eczema affects approximately 1 in 5 children in the UK, making it one of the most prevalent childhood skin conditions. The NHS reports that most cases develop before a child's fifth birthday, with the majority presenting in the first year of life. Many children — around 60 to 70 percent — will see significant improvement or complete resolution of their eczema by adolescence, though some will continue to have it into adulthood.

What It Looks Like at Different Ages

The appearance and location of eczema changes as a child grows.

In babies under 12 months, eczema most commonly appears on the face — particularly the cheeks and forehead — as well as the scalp, outer arms, and legs. The nappy area is usually spared, which helps distinguish eczema from nappy rash.

In toddlers and older children, the pattern shifts. Eczema tends to concentrate in the skin folds — the inner elbows, the backs of the knees, the wrists, and sometimes the ankles and neck. The patches may be dry and scaly when not actively inflamed, and redder, weeping, and intensely itchy during a flare.

In all ages, eczema causes itching that can be severe. Babies who cannot scratch may rub their face against bedding or clothing. Disturbed sleep from itching is very common and can be one of the most exhausting aspects of managing the condition for families.

Diagnosis

There is no blood test or skin test that diagnoses eczema. Diagnosis is clinical — a GP or dermatologist makes the diagnosis by examining the skin and reviewing the history. They will look at the pattern of involvement, the appearance of the rash, and whether there is a family history of atopic conditions.

It is worth ruling out other causes of a rash in infants, including seborrhoeic dermatitis (cradle cap, which tends to be greasy rather than dry), contact dermatitis (a reaction to a specific irritant that touches the skin), and fungal infections. A GP can help distinguish between these.

Common Triggers

Eczema is not caused by a single trigger, and identifying what makes an individual child's skin flare is an important part of management.

Dry air and cold weather remove moisture from already-compromised skin. Conversely, excessive heat and sweating can also provoke itching.

Wool and synthetic fabrics are common irritants. Dressing a baby with eczema in soft cotton or bamboo fabrics, and using cotton bedding, helps reduce skin irritation.

Soaps, bubble baths, scented wipes, and fabric softeners can all disrupt the skin barrier. NHS guidance is clear: use only emollient wash products on a child with eczema — not standard soap or baby wash.

Environmental allergens including house dust mites and pet dander can worsen eczema in some children. Keeping soft furnishings and mattresses covered with dust mite-proof covers and washing bedding weekly at 60°C may help.

Stress and illness can provoke flares. It is common for eczema to worsen when a child is teething, starting nursery, or recovering from a cold.

The Emollient-First Approach

Moisturisers — called emollients in the context of eczema treatment — are the cornerstone of management. The NHS and British Association of Dermatologists both emphasise that emollients should be applied to all skin, not just visibly affected areas, at least twice daily every day — including during periods when the skin appears clear. This is not optional additional care; it is the primary treatment.

Regular emollient use reduces the frequency of flares, reduces the amount of steroid cream needed, and improves the skin barrier over time.

How to Apply Emollients

Apply in the direction of hair growth (downward strokes on arms and legs) to reduce the risk of folliculitis — irritation of the hair follicles. Use generous amounts — a child with eczema covering a significant area of the body may need 250g to 500g of emollient per week.

Apply within a few minutes of getting out of a bath or shower, while the skin is still slightly damp. This helps lock in moisture. Pat — do not rub — the skin dry first with a soft towel.

Types of Emollient

Emollients range from light lotions to thick ointments. As a general rule, the more severe the dryness, the thicker the product needs to be.

Lotions are the lightest — mostly water. They feel pleasant and absorb quickly but provide the least protection and may contain preservatives that irritate sensitive skin.

Creams are a middle ground — a mix of water and oil. Products such as Diprobase cream, Cetraben, and Doublebase are commonly prescribed. They are suitable for daily use and easier to apply than ointments.

Ointments are almost entirely oil with very little water. Hydromol ointment and white soft paraffin (petroleum jelly) are the most effective for very dry, thickened skin. They feel greasy and can be harder to use during the day, but are excellent for overnight application.

Many families use a lighter cream during the day and an ointment at night. GPs can prescribe emollients on a repeat prescription — buying adequate quantities over the counter can become expensive, and children with moderate-to-severe eczema are entitled to prescription emollients.

Bath Guidance

Bathing should be daily if possible — it removes irritants, allergens, and bacteria from the skin. However, the water should be lukewarm rather than hot, and the duration should be kept to around 5 to 10 minutes. Soaking longer in hot water dries the skin.

Add an emollient bath oil or use an emollient wash product instead of soap or baby wash. Never use bubble bath, which strips the skin barrier. Rinse the skin thoroughly and pat dry with a soft towel.

Apply emollient immediately after drying — within 3 minutes — before the skin has time to dry out again.

Steroid Creams

Topical corticosteroids are safe and effective when used correctly. They are the main treatment for eczema flares and should be used alongside — not instead of — emollients.

The weakest steroid cream available over the counter is 1% hydrocortisone. This is appropriate for mild eczema flares on the face, neck, and skin folds. Stronger steroids (such as clobetasone butyrate 0.05% or betamethasone valerate 0.1%) are available on prescription and used for more resistant areas or more severe flares — but not routinely on the face.

A useful measure is the fingertip unit (FTU): one FTU is the amount of cream from the tip to the first crease of an adult index finger, and is enough to cover an area twice the size of an adult hand. Following FTU guidance helps avoid under-treating (which prolongs a flare) or over-applying.

Steroid creams should be applied to visibly inflamed, affected areas once or twice daily during a flare. They should not be used on unaffected skin. Once the skin has cleared — usually within 5 to 7 days — the steroid is stopped and you return to emollient-only maintenance.

Concerns about steroid creams thinning the skin are understandable, but skin thinning (atrophy) occurs with prolonged daily use of mid-to-high strength steroids on the same area. Short courses of low-strength steroid cream as directed, with periods of clear skin in between, are very safe. Discuss any concerns with your GP or pharmacist.

Wet Wrapping

Wet wrapping is a technique used for severe eczema flares when standard treatment is not controlling symptoms. It involves applying a thick layer of emollient and/or diluted steroid cream to the skin, then covering with a wet bandage or wet tubular bandage, topped with a dry layer. The wet layer creates an occlusive environment that drives moisture into the skin and dramatically reduces itching.

Wet wrapping is not a first-line home treatment — it should be introduced under guidance from a GP or dermatologist who can show you the correct technique and prescribe appropriate products.

Infected Eczema

Eczema that is infected looks different from a regular flare. Signs of infection include:

• Weeping, crusted, or honey-coloured patches (suggesting bacterial infection, usually with Staphylococcus aureus)
• Yellow fluid or pus
• Rapid worsening despite usual treatment
• Fever or your child seeming generally unwell

Infected eczema needs antibiotic treatment — usually oral antibiotics from a GP. A topical antibiotic alone is generally not sufficient for widespread infection. If your child's eczema appears infected, see a GP promptly rather than waiting.

A more serious complication is eczema herpeticum — a viral skin infection caused by herpes simplex virus spreading across eczematous skin. It causes punched-out ulcers, pain, and rapid spread across the skin. This requires urgent medical attention and antiviral treatment.

When to Refer to a Specialist

Most eczema in babies and toddlers can be managed by a GP. Referral to a paediatric dermatologist or allergy specialist is appropriate when:

• Eczema is severe and not responding to topical treatments
• There is suspected food allergy triggering the eczema
• Infections are frequent
• The family needs specialist support with wet wrapping or allergen management
• The diagnosis is uncertain

The Food Allergy Connection

Research suggests that approximately one third of children with moderate-to-severe eczema have an IgE-mediated food allergy — meaning their immune system produces antibodies to a food that then trigger allergic reactions. The most common foods involved in children with eczema are cow's milk, egg, peanut, wheat, and soy.

It is important to understand that food allergy does not cause eczema in the way a trigger causes an immediate reaction. The relationship is complex. A child with eczema-associated food allergy may find that the eczema is harder to control, and that accidental ingestion of the trigger food leads to an acute flare or other allergic symptoms such as hives.

Do not eliminate foods from your child's diet without proper allergy testing. Unguided dietary restriction risks nutritional deficiency and can sensitise the child to foods they have not been properly challenged with. If you suspect a food allergy is playing a role in your child's eczema, speak to your GP about a referral for allergy testing — skin prick testing and specific IgE blood tests are the appropriate investigations.

Paradoxically, the current guidance from the AAP (American Academy of Pediatrics) and the NHS is to introduce potentially allergenic foods early — including peanut — to reduce the risk of developing food allergy, not to avoid them. Early introduction in infants with eczema has been shown in clinical trials to reduce peanut allergy rates significantly.

Frequently Asked Questions

Will my baby's eczema go away on its own?

Many children do see significant improvement as they grow older. Research suggests that around 60 to 70 percent of children with eczema will have clear or near-clear skin by their teenage years. However, some will continue to have flares into adulthood, particularly during periods of stress or illness. Good skin care habits established early — daily emollients, avoiding known triggers — give the best foundation for long-term control.

Can I use aqueous cream on my baby's eczema?

Aqueous cream is no longer recommended as a leave-on emollient. It contains sodium lauryl sulphate (SLS), a detergent that can actually damage the skin barrier with regular use. It may still be used as a soap substitute in the bath. For daily moisturising, choose an SLS-free emollient such as Diprobase, Cetraben, or Hydromol.

How do I stop my baby scratching?

Keeping fingernails short and smooth is important. Cotton scratch mitts can be used in young babies during sleep, though they become harder to keep on once babies are more mobile. Keeping the bedroom cool at night — eczema itching typically worsens with heat — and applying an emollient or steroid cream to treat the inflammation directly will reduce the itch more effectively than physical barriers alone.

Is eczema caused by something I did during pregnancy?

No. Eczema is largely determined by genetic factors and immune system development. There is no evidence that a mother's diet during pregnancy, how she fed her baby, or her household cleaning habits caused the eczema. This is an important point for parents who feel guilty — the condition is not the result of anything you did or did not do.

Should I use a prescribed emollient or buy one over the counter?

For children with persistent eczema, prescription emollients make financial sense. Emollients need to be used in large quantities — a child may go through hundreds of grams a week — and the cost of buying them over the counter mounts up quickly. Your GP can prescribe emollients on a repeat prescription. Discuss which product works best for your child's skin type.

Can eczema affect my child's sleep and development?

Yes — the itching associated with eczema is often worst at night, and disrupted sleep is one of the most significant impacts on quality of life for both children and parents. Chronic sleep deprivation can affect a child's mood, concentration, and development, and parental sleep deprivation compounds the difficulty of managing a demanding condition. If sleep disruption is severe, discuss this with your GP, who may recommend evening topical treatment strategies or refer to a specialist nurse for additional support.

Original Insight: Eczema Management Is About Prevention, Not Just Treatment

Parents ask about steroid cream strength, frequency, and escalation plans—but eczema care is actually built on the foundation of what you do every day when there's no flare happening. Applying emollient twice daily, every single day, feels boring and preventive when your baby's skin looks fine. This feels less important than the drama of a full-body flare requiring stronger steroids. But here's the clinical reality: consistent daily emollient use reduces the frequency of flares by 30-50% and can reduce steroid use by half. The babies with the worst eczema outcomes are often those whose parents do well during flares (using prescribed treatments, being attentive) but slip on daily maintenance during clear periods. Once the skin looks better, the daily routine feels unnecessary. Then the barrier breaks down again and the cycle repeats. Additionally, if your baby has eczema and you're considering food elimination diets, this is where many parents go wrong. About one-third of children with moderate-to-severe eczema have a food allergy. But about two-thirds do not. Eliminating foods without proper testing creates unnecessary restriction, nutritional gaps, and can actually make eczema worse if the eliminated food contained important nutrients. Get proper allergy testing through your GP before removing anything from your baby's diet.

Key Takeaways

• Eczema (atopic dermatitis) affects around 1 in 5 children in the UK and usually first appears before age 1. It is a chronic inflammatory condition, not a contagious infection, and not caused by anything the parent did.
• The skin barrier in eczema is defective — it loses moisture easily and lets irritants in. Daily emollient use, twice or more, is the most important treatment at every stage, not just during flares.
• Use emollients generously on all skin, applying within 3 minutes of bathing. Ointments provide the most protection for very dry skin; creams are more practical for daytime use.
• Avoid soap, bubble bath, scented products, and fabric softeners. Use emollient wash products in the bath instead.
• Steroid creams treat active flares. Low-strength 1% hydrocortisone is available over the counter; stronger creams require a prescription. Short courses used correctly are safe.
• Infected eczema — weeping, crusted, rapidly worsening — requires prompt medical attention and antibiotic treatment.
• Approximately one third of children with moderate-to-severe eczema have an associated food allergy. Do not eliminate foods without proper allergy testing through your GP.
• Most children improve significantly as they grow older. With consistent daily skin care, flares can be kept to a minimum.
• Always consult your GP for personalised advice, especially if standard treatment is not controlling symptoms.
