Newborn babies are prone to all sorts of rashes, most of which are harmless and will clear up on their own without treatment. Babies’ skin can form pink pimples, called neonatal acne, that can last for weeks or months on the baby’s skin, with no treatment needed. Another common newborn rash is erythema toxicum which has red blotches with undefined borders that are slightly raised and possibly a white or yellow dot in the center. This one also resolves itself within a few days or weeks without treatment. Blocked oil glands can cause little white bumps on the nose and face that will disappear as the baby’s oil glands enlarge naturally. Salmon patches can appear on the back of the neck or between the eyes and are the result of blood vessels pooling that are harmless. A greasy, yellowish crust on the baby’s scalp is a sign of a cradle cap, which your doctor can tell you how to treat based on the symptoms. Eczema is another rash, this time with red, itchy patches, that your doctor can determine a treatment plan for if needed. Prickly heat shows up with small red bumps, particularly in areas where the baby overheats, such as the neck, armpits, and diaper area, and is treated by keeping the baby’s skin dry. Babies can also get fungal infections on the tongue, in the diaper area, and in skin creases. On the tongue, it is known as thrush and appears to be dried milk that can’t be scraped off. On the skin, it shows up as an intense red rash with small bumps around the perimeter. It can be treated with antifungal medications.
