my baby is not keeping head up. seeing either sides all the time and sleeping by keeping head either side. will it cause flat head?

A. Flat head in Babies is very common mostly on one side initially when the baby is not flipping on the sides in the first few months . so because of the continuous pressure over the soft skull bones such flattening can be there . This will become normal by itself gradually when the skdeull grow in size and shape with age . No musturd seed pillow or any such kind of intervention like massage is required for the corrrction .
