My soon to be five year old cries about everything. If he doesn't get his way he cries. He hits his aunts and sister when they don't do what he wants. When he hears sudden noises he gets scared. Noises with high pitch causes him to cover his ears. When family members want to hug him he yells at them that he doesn't like them, or says don't talk to me. He smells his food only eats what smells pleasing to him. If I change the ingredients of food he knows just by smelling it and refuses to eat. He is very clingy to me.He has been in school since he has been 3, and his teachers say he doesn't express this behavior in class. When he was a baby he never liked the sun on his face no loud noise he would always cover his ears. Always smelling everything and never like when females talked to him or wanted to hug him only males. He was a late talker at the age of three. He expresses himself clearly. I'm helpless on how to deal with his behavior.
