It is a common clinical reality in the United Kingdom that both eczema and psoriasis can appear very early in life. Atopic eczema is particularly prevalent, affecting approximately one in five children in the UK, often developing before a child’s first birthday. While psoriasis is less common in infants, it can still occur, sometimes appearing as early as the first few months of life. Identifying these conditions early is vital, as the skin barrier of a baby or toddler is significantly thinner and more delicate than that of an adult. Correct management not only soothes the immediate discomfort but can also help prevent the long-term cycle of skin damage known as the “atopic march.”

Identifying atopic eczema in infants
Atopic eczema (infantile eczema) usually appears between the ages of two and six months. Unlike adult eczema, which often affects the creases of the elbows and knees, eczema in babies typically starts on the face and scalp.
- Appearance: The skin looks red, dry, and scaly. In severe cases, it may weep or crust, which can be a sign of a secondary bacterial infection.
- Behaviour: Babies may become restless or have trouble sleeping due to the intense itch. You might notice them rubbing their face against bedding or their parents’ clothing for relief.
- Evolution: As a child reaches toddlerhood and begins to crawl, the eczema often moves to the outer surfaces of the limbs (extensor surfaces) like the fronts of the knees and the outsides of the elbows, where friction is highest.
Psoriasis in babies: The “Nappy Psoriasis” factor
Psoriasis in infants is less frequent but often presents in specific ways that can be confused with a standard nappy rash.
- Nappy Psoriasis: This appears as well-defined, bright red, shiny patches in the nappy area. Unlike standard nappy rash, which is often patchy, psoriasis is usually very symmetrical and has sharp edges.
- Scalp Involvement: Psoriasis can cause thick, silvery scales on the scalp. This is often more persistent and “heavier” than common cradle cap.
- Guttate Psoriasis: In toddlers, a sudden outbreak of small, drop-like red spots can occur following a viral or bacterial infection, such as a sore throat.
Why does it happen? The Atopic Triad
In the UK, the NHS highlights that childhood eczema is strongly linked to a family history of allergies. This is known as the “atopic triad.” If one or both parents have eczema, asthma, or hay fever, a child is significantly more likely to develop a skin condition. This is due to a genetic weakness in the skin’s ability to produce filaggrin, a protein essential for maintaining the skin barrier. When this barrier is weak, allergens like dust mites, pet dander, or even certain foods can trigger an inflammatory response.
Safe management for young skin
The primary goal for treating babies and toddlers is to support the skin barrier without using harsh chemicals.
Bathing and Cleansing
- Lukewarm Water: Never use hot water, as it strips away the limited natural oils in a baby’s skin.
- Soap Substitutes: Avoid all “baby bubble baths” and scented soaps. Instead, use a medical-grade emollient as a wash.
- Pat Dry: Never rub a baby’s skin with a towel; gently pat it dry to avoid friction-based irritation.
The Emollient Routine
Emollients are the most important part of treatment. They should be applied frequently, ideally at every nappy change, even when the skin looks clear. In the UK, many effective emollients like AproDerm, Epimax, or Doublebase can be prescribed by your GP.
Targeted Medicated Creams
If the skin is red and inflamed, a GP may prescribe:
- Mild Topical Steroids: Such as 1% hydrocortisone, used for short bursts (3 to 7 days) to calm a flare-up.
- Non-Steroidal Creams: For sensitive areas like the face, a GP might suggest calcineurin inhibitors, though these are typically reserved for children over the age of two.
When to see a GP
While many mild rashes can be managed at home, you should seek medical advice if:
- The rash is spreading rapidly or appears painful.
- The skin is weeping, bleeding, or has yellow/golden crusts (signs of infection).
- Your baby is unusually fussy or unable to sleep due to itching.
- The rash does not improve after a week of consistent emollient use.
- You notice small, punched-out blisters (which could indicate a viral infection like eczema herpeticum).
Conclusion
Babies and toddlers can certainly develop eczema and psoriasis, and while it can be distressing for parents, the vast majority of cases can be well-controlled. By maintaining a rigorous routine of soap-free washing and frequent moisturising, you can protect your child’s delicate skin barrier and reduce the frequency of painful flares. Many children find that their eczema improves significantly or even disappears entirely as they get older, but early and consistent care is the best way to ensure their skin remains healthy throughout their childhood.
How can I tell if my baby has eczema or psoriasis?
Eczema typically presents as red, dry, and itchy patches, often on the face and scalp. Psoriasis in infants is rarer and often appears as symmetrical, bright red, shiny patches in the nappy area or as thick, persistent scales on the scalp.
What is the “atopic triad”?
The atopic triad refers to the common genetic link between eczema, asthma, and hay fever. If there is a family history of these conditions, a child is more likely to develop eczema due to a weakened skin barrier.
How should I bathe my child if they have sensitive skin?
Use only lukewarm water and avoid all scented soaps or bubble baths. Always use a prescribed emollient as a soap substitute and gently pat the skin dry with a towel instead of rubbing.
How often should I apply emollients to my baby?
You should apply emollients liberally and frequently, ideally at every nappy change. Consistent use is essential, even when the skin appears clear, to maintain a healthy barrier.
Is it safe to use steroids on my baby’s skin?
Mild topical steroids, such as 1% hydrocortisone, can be prescribed by a GP for short, controlled bursts to calm inflammation. Always follow your doctor’s instructions regarding frequency and duration to ensure safety.
When should I seek medical help for my child’s skin?
See your GP if the rash spreads rapidly, appears painful, weeps, or has golden crusting. Additionally, consult a doctor if your child is struggling to sleep or if the condition does not improve with consistent emollient use.
