Harrison keeps hitting himself on the head If hes angry, tired, upset... he smacks himself with both hands over and over again. If hes playing he will quite often use what ever hes playing with to bang on his head. If he bumps his head by accident he will do it again, sometimes laughing sometimes crying. (Hes always done this) He hits me and his dad for fun. We always say 'no dont smack it hurts' or 'mummy doesnt smack you so please dont smack mummy' etc etc. This is stuff thats started happening recently i understand it could be frustration but it just seems lke a little bit more than that to me Normal toddler? or something i should mention to the hv on monday?
