I'm a caregiver to a 5 year old who constantly, while sitting rocks back and forth. He also bites his clothes and himself on his hands. He has meltdowns over the littlest things. He has now started blinking his eyes, usually one at a time, over and over again. He insists on eating the same thing everyday, and it has to be placed on his plate in certain way. He also has problems relating to other children, and is always hitting them. I would appreciate any advise on what I could do to help him.
