My baby is 11 months and 16 days old. His weight is 7.8. He is not gaining weight. He keeps hitting his head but does not cry. He just does this. Please tell me if he is having any problem.

A. Namaste Mom, Hitting his head ? is he been doing since long time or its recently you noticed this ? one reason is heavness in the head due to teething, but if he is been doing quite often then he need to be examined
