When you have a newborn, you may expect diaper rash and cradle cap. But what about those tiny white bumps across your baby's nose and chin? This complexion problem is known as milia.

Although milia can develop at any age, the tiny white bumps are most common among newborns. In fact, about half of all babies develop milia. There's little you can do to prevent milia. If your baby has milia, the best treatment is usually none at all.
