Many new parents become alarmed by the sudden appearance of a rash on their baby's face. With so many possible underlying conditions, it is hard not to worry. Rashes are quite common, though, and, most of the time, they are no cause for concern. The most common skin disorders appear seemingly at random and disappear without treatment. However, some bumps and spots are signs that your little one needs a doctor's help.
Erythema toxicum neonatorum is the most common rash in healthy newborns, affecting about 50%. This benign condition develops as reddish blotches ranging from 1 to 3 centimeters in diameter, with tiny blisters or clear sacs in the middle. A baby may have just one or two, or hundreds of these spots. This noninfectious rash can turn up on the face and limbs but primarily appears on the trunk. It typically emerges at one or two days old but sometimes flares up around the fourth day. The little blisters do not seem to irritate infants, and they clear up spontaneously within three to seven days.
