What should you know about cradle cap body rash?

Infantile seborrheic dermatitis can affect oily or folded skin such as the eyebrows, behind the ears, neck, armpits, and nappy area. The rash may be pink or red with fine, greasy, or flaky scale. A body rash is not automatically part of cradle cap, especially when it is widespread or intensely itchy.

Heat rash, eczema, contact irritation, and infection can produce similar changes. Note whether the rash is dry or wet, where it began, whether it follows folds, and whether your child seems comfortable. These observations help a clinician distinguish patterns.

Use lukewarm water and a mild, fragrance-free cleanser, then pat rather than rub. Keep skin folds clean and dry, change damp clothing, and avoid new scented products while the rash is active. Do not apply steroid, antifungal, or combination creams without advice for a child. A clinician can explain [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) and, when appropriate, [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/).

Arrange a medical review for a rash covering several body areas, worsening despite gentle care, or causing significant itch, cracks, oozing, or sleep disruption. Seek urgent help for fever, blisters, purple or bruise-like spots, facial swelling, breathing difficulty, or a child who is difficult to wake or feeding poorly. Rapid spread also warrants prompt advice.

Ask whether the body pattern fits seborrheic dermatitis, eczema, irritation, or infection, and which products are safe for each affected area. Bring a list of recent soaps, creams, detergents, medicines, and foods, and describe how quickly the rash changed.
