Are helmets the only way to reshape a child's head?

Depends: We don't have enough information to answer this question. It depends on age, & degree of the problem. Sometimes surgery is an option, but it is a very serious surgery. Talk to your doctor about the specifics in your case and all the possible treatments. Get a second opinion, if you wish.(take all the records with you when you do) In fact, getting a second opinion on any serious problem is smart!
