The golden rule: don't treat

Almost all of it resolves on its own. No scrubbing, no squeezing, no acne products, no heavy lotions on the face. Warm water and patience outperform every product for these.

Is this normal for your baby?

FirstWeeks answers with your baby’s age and today’s log in mind — with pediatric sources attached.

Cradle cap

Yellowish scales on the scalp — commonly seen for months. A soft brush during baths, optionally a little plain oil before, lifts flakes gently. It doesn't itch or bother the owner.

Diaper-zone care

Frequent changes, pat dry, air time, and a zinc barrier cream at the first sign of redness — prevention is nearly the whole game.

When skin earns a call

Blisters or pus-filled bumps, a rash plus fever 100.4°F+, raw bleeding areas, or a rash that makes the baby miserable — those are pediatrician territory, same day.
