My son is 3years old.He was dianosed with autism in December of 2006.He has such a hard time following instructions,and simple commands.He gets very aggravated when things don't go his way (just like a typical toddler).I can't not let him walk with his father or I in a store because he will run off.We get down on one knee,look him in the eye and tell him that he's not to run off,and that he's to stay with mommy and daddy but still yet he does not listen.He looks at us as if he does not understand what we are saying.I am in such need of help.
