He is in a world of not knowing anything but frustration, he bites himself all the time, very seriously down his entire arms, he sleeps curled up on floors with his comfort blanket, trys to communicate with loud (Aggggg) outbursts, has never been to a special school, does he know anything around him? what can family do to help him grow and be somewhat content, I feel he is always in pain, and his parents use medications the doctor prescribed to keep him drugged all the time. he bangs his head against walls etc. does he even know that we are there?
