Helmet therapy for plagiocephaly is always a choice; it’s never mandatory. It can be helpful in the right situation, but it’s not always needed. The head shape does often get better, with or without the use of a helmet. Helmet therapy is a choice some parents make, along with their child’s doctor, to try to cosmetically improve the shape of a child’s head. With your pediatrician, or a pediatric neurosurgeon, you can discuss your baby’s specific case and the pros and cons of helmet therapy.
