A. hi dear Many newborns develop a blotchy red skin reaction called erythema toxicum, which can appear between 2 days and 2 weeks after birth. Flat, red patches or small bumps often first appear on the face and spread to the body and limbs. The rash is harmless, not contagious, and will clear after a few days or a week.
