Cradle cap
Overview
Cradle cap is a common, harmless form of infant seborrhoeic dermatitis that produces greasy scales, usually on the scalp. It is not contagious and often clears within months.
Babies develop rapidly, and the same condition can look different from one child to another. This guide supports informed conversations with a health professional; it cannot diagnose a baby or replace individual care.
Signs and symptoms
White or yellow scales may form a crust on the scalp, eyebrows or skin folds. It generally does not itch or trouble the baby.
Parents know their baby best. A change in feeding, alertness, breathing, colour, temperature or wet nappies can be as important as one isolated sign, especially in the newborn period.
Causes
Its exact cause is unclear; active oil glands and normal skin yeast may contribute. It is not caused by poor hygiene.
Risk factors
Risk depends on the condition. Prematurity, a difficult birth, infection exposure, feeding difficulties, family history or another medical condition may matter, but many affected babies have no obvious risk factor. Risk factors do not confirm a diagnosis.
Diagnosis
The appearance is usually enough for diagnosis. Widespread, inflamed or weeping skin may need review for eczema or infection.
A clinician may review pregnancy and birth history, feeding, growth and symptom timing before examining the baby. Tests are chosen only when the history or examination suggests they will help.
Treatment options
Gentle use of an unperfumed emollient, soft brushing and baby shampoo can loosen scales. Do not pick crusts or use adult medicated products without advice.
Medicines, specialised feeds, procedures or monitoring should be used only on advice from the baby’s healthcare team. Never give a newborn over-the-counter medicine unless a qualified professional has confirmed the product and dose.
Home care
Keep a simple record of feeds, wet and dirty nappies, sleep, temperature when advised, and changes in symptoms. Follow safer-sleep guidance, wash hands before baby care, attend follow-up appointments and ask for help if feeding is painful or ineffective.
Prevention
Not every condition can be prevented. Antenatal care, recommended newborn screening, smoke-free surroundings, good hand hygiene, safe preparation of feeds, scheduled immunisation and prompt assessment of an unwell baby can reduce avoidable harm.
Possible complications
Most mild newborn problems improve without lasting effects, while some conditions need prompt treatment to protect feeding, growth, breathing, hearing or development. The healthcare team can explain the outlook for the individual baby and arrange follow-up when needed.
When to seek urgent medical care
Arrange review if skin becomes swollen, painful, bleeding or weeping, spreads widely, or the baby seems unwell.
Seek urgent help for a baby who is difficult to wake, unusually floppy, struggling to breathe, turning blue or very pale, having a seizure, repeatedly vomiting green fluid, feeding much less, or producing notably fewer wet nappies. A fever or abnormally low temperature in a young baby needs prompt professional advice.
Frequently asked questions
Is this my fault?
No. Newborn conditions usually arise from development, feeding, infection, birth-related factors or causes outside a parent’s control.
Can I continue feeding my baby?
Often yes, but the safest plan depends on the condition and how well the baby feeds. Ask promptly if feeds are tiring, painful, repeatedly vomited or much shorter than usual.
When should I arrange follow-up?
Use the timeframe given by the maternity, neonatal or primary-care team. Arrange an earlier review if symptoms worsen, feeding changes, growth is a concern or you remain worried.
Summary
Cradle cap is usually self-limiting and responds to gentle skin care. Early assessment is especially important in young babies because they can become unwell quickly.
