If a newborn develops a rash all over their body, it can be alarming, but not all rashes are dangerous. Here’s what parents should know and watch for:

Common (Usually Harmless) Newborn Rashes:

1. Erythema toxicum neonatorum:

   • Red spots with small white/yellow bumps.

   • Common in healthy newborns (first week of life).

   • No treatment needed; clears on its own.

2. Milia:

   • Tiny white bumps on the nose, cheeks, or chin.

   • Caused by blocked skin pores; resolve without treatment.

3. Newborn acne:

   • Pimples on face, usually around 2–6 weeks of age.

   • Caused by maternal hormones; typically resolves in a few weeks/months.

4. Heat rash (prickly heat):

   • Small red bumps in skin folds or where the baby gets hot.

   • Keep baby cool and dry; usually resolves quickly.

Warning Signs — When to Call a Doctor:

• Fever (≥100.4°F or 38°C) in a baby under 3 months.

• Rash looks like bruises or purple spots (could be serious, like meningitis).

• Rash with blisters, peeling skin, or open sores.

• Baby is very sleepy, irritable, or feeding poorly.

• Rash is rapidly spreading or the skin looks infected (red, swollen, warm).

What Parents Should Do:

• Don’t apply creams or powders unless recommended by a doctor.

• Keep baby’s skin clean and dry; dress in soft, breathable clothing.

• Take pictures to document changes if you need to consult a doctor.
