Several of the babies in my son's playgroup had misshapen heads, due to their position in the womb. (They were large, their moms were small; fact of life and nothing the moms did or didn't do!) Both babies ended up seeing a specialist who had them wear a helmet for a few months to help reshape their heads. It was NOT painful - the kids never even felt it that we could tell - and the moms, after the initial OHNOESNOTMYCHILD reaction, had fun with it and decorated the helmets with stickers and their names! The rest of us were actually JEALOUS - we have hardwood floors and my son falls constantly, he totally could have used a helmet! I would talk to your pediatrician again, and if you don't like the answer, get a second opinion. At this age, a misshapen head is completely correctable. In fact, I saw one of the babies in question this morning during playgroup, and you'd never have known he had a misshapen head a year ago! Good luck!
