What are the small bumps in my baby's mouth?

Q: The roof of my baby's mouth is covered with small white bumps. What are they?

A: Don't stress -- they're probably just harmless cysts, known as Epstein's pearls, which will disappear as your baby gets older. However, if you spot big, blotchy white areas growing in your child's mouth (even on her tongue), it could be thrush -- a type of yeast infection. Visit your child's doctor, who'll probably prescribe an antifungal medicine, like Nystatin. --Sharon Anne Waldrop
