My baby while sleeping turns his head on left side but after changing the position she again turns his head to previous one. But baby head is flat on left side. Is this a problem or any suggestion about this

A. That’s because when you are saying very clearly that your child is always turning the head towards left side then that is why the head has become flat so to break this habit it would be good currently that you start using a follow pillow with which when you keep the head into that the child would be bound to keep the head straight and since it is going to be hollow it is not going to touch the bed so the head is not going to become flat from back and slowly this way the left side of the head which has become Flat is going to retain its position
