Hello doctor, my baby is 4 months old girl. She keeps on scratching her head (pulling and leaving her hair opening and closing fingers on hair) specially when shes sleepy or when noone is near or talking to her. is this repetative behaviour normal??also she dosnt grab toys if i give in her hand she throws them within 10 seconds. She smiles when someone smiles at her. She holds her head and rolls to one side and from back to front pushes things away from her legs and wants to stand all time. talks too much (agu) likes to be held and played with and makes good eye contact. still dosent make gesture to come to parents IS THIS NORMAL OR SIGN OF AUTISM?
