Hello, I went through your query, it could beflat head syndrome, also called positional plagiocephaly. Flat head syndrome usually happens when a baby sleeps in the same position most of the time or because of problems with the neck muscles.This problem does not harm brain development or cause any lasting appearance problems. And, fortunately, it does not require surgery. Simple practices like changing a baby's sleep position, holding your baby, and providing lots of "tummy time" can help.
