Q&A: Why Is Baby's Head Flat?

Why is baby's head still flat?

Now that babies are all sleeping on their backs, many babies are getting what’s called "positional plagiocephaly," or flat heads. This usually resolves itself with lots of tummy time — I suggest after every diaper change — so babies have time when they’re not on their head. Occasionally your pediatrician may recommend a positioning helmet, which helps to reshape the head. By putting babies on their stomach from day one, most parents can avoid ever needing the helmet, so tummy time is important!
