Mera beta 3 month ka hai .. uska head ek side se flat ho gya h.. what should i do

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 . ytThis will become normal by itself gradually when the skull grow in size and shape with age . No musturd seed pillow or any such kind of intefrvention like massage is required for the corrrction .
