About

Positional plagiocephaly is the term used to describe asymmetric or flattened head shape, usually on one side or the back of your baby's head. It is caused by pressure on the bones of the skull before or after birth. Many babies develop plagiocephaly by sleeping regularly in one position, or by spending extensive time sitting in the same position in a car seat or swing.
