Re: bad eating manners..
My son is 7 and still reverts to eating with his hands sometimes. He doesn't have a temper problem so we just keep reminding him to use his fork or spoon when he starts that. He also will occasionally throw his food around or on his head if we aren't watching him. I really don't have an answer, just wanted you to know it's not just your son. Good Luck (to us all!)
