My 5 year old son, when he gets excited over something, he jumps up & down, starts moving his hands rapidly (like shaking his hands off) & sometimes will even rolls his eyes. He also started twriling his hair on his finger that his finger gets stuck & he pulls his finger out & hair comes out with it, his dad had this "habit" when he was a child. However, when we remind him his doing it he stops. Any comments would be appreciated or any direction. We have an appointment to take him to PscyD but wanted to do a little research before we go out so we are prepared with questions. Thank you!!
