hi.. my baby is 4 months 10 days old and started rolling but couldnt hold up his head steadily. some people are saying that due to heavy weight of the head on the back side i.e, due to flattened head it will take time to hold his head steadily. is it true? when i told about flattened head to the paeditrician in the 3rd month, he said it will be set in the 5th month. will my baby's head come to normal shape?? any treatment to be given for that?? please let me know as im very worried about this
