This rash is also called erythema toxicum. It is a common skin condition that affects many newborns. It is not serious and isn't contagious.
The rash may appear as small blisters on a red base. The blisters may have a white or yellow liquid inside. Sometimes there are just red spots. The rash may be present at birth, but it more often appears within 24 to 48 hours after birth. In most cases, it goes away within 1 week. Usually no treatment is needed.
