common skin conditions in newborns and infants also include baby “acne” or erythema toxicum. these typically appear in the first few days after birth and tends to fades within a week. it’s theorized that the red, blotchy rash is triggered by hormones passed from mother to child through the placenta and breast milk, which aggravate sebaceous glands and lead to little, raised spots. these pimples usually appear on the cheeks, nose, and forehead, but they can also appear on the neck, back, or chest.
cradle cap—marked by thick, crusty, oily, or scaly patches or patches of yellow, greasy crusts—usually develops in the first few months after birth and typically clears up on its own within a few weeks. while it usually affects the scalp, it can also appear on the face, armpits, and groin.
then, there’s diaper rash, possibly the most common skin condition in babies worldwide. it’s characterized by pink or red patches on their bottom, which may feel hot to the touch, and skin that appears irritated and inflamed. spots, pimples, scaling, or blisters may also develop. severe diaper rash can cause discomfort and distress.
“it doesn’t matter if you use cloth diapers or disposable diapers, or how expensive your diapers are; diaper rash really comes down to how frequently you change the diapers,” says jill sommerville, director of medical at waterwipes. “leaving wet diapers on for a long time or a diaper that has poo in it can have a negative effect on the skin. because it’s sealed tightly, a diaper becomes like an incubator, and urine on the skin can begin to damage it. if you don’t change a diaper quickly enough or if you wipe the bottom then put a diaper on straight away when the bottom hasn’t had a chance to dry, it can be a bit nasty for a baby or sore for them.”
