hi my baby is active n happy three years boy. normally he listens my words sometimes he won't listen. but the problem is he sometimes plays with our neighborhood boy who is seven years. whenever they play together my boy become excited too much and likes to run jumping always. he started throwing things. for example his friend bring building blocks to play then my baby throw them definitely and laugh.he is just like an excited boy that time who is unstoppable.even if suppose they play outside then he is running and jumping and playing but not getting the actual game properly. does his behaviour is normal?? but with other children he is quite normal I noticed. He is always excited to this boy and his family. he behaves like to throw things in front of them rather than alone time. he knows not to throw yet he do it infront of them. is this phase will go soon?? or its really a problem??
