Most likely, the newborn's acne is caused by hormones passed from mother to baby in the last stage of pregnancy. Newborn acne can be irritated by contact with spit up, formula, rough fabrics, harsh detergents, and soaps. Certain viral illnesses, allergies, and medications can cause an acne-like rash, so i would be wise to consult the baby's physician.
