Hungry

I put my cell phone down and closed my laptop.
I muted the television. I turned my attention to him. There he was banging his head with his hand as he was making the "duh duh doo duh duh duh" sound. Then after a minute or so of that, he started to jolt his body on the arm of the chair and vocalizing "ch ch ch ch " ....that went on for about one minute. He then jumped down from the chair and began to roll on the floor this time "haaaa ooooo haaaa"
and then he jumps up, runs over to me and screams in my face "I'm hungry!!" Then he stomps away back to the chair.

I sat with that thought. He is hungry but for what, I am not really sure.
I feel like he is constantly needing stimulation. I was told a few years ago that this is a result of his inability to be visually stimulated. I don't know what it is to live in his world. A world that must be related to through sound, smell, touch and hearing only. A world where the very people who are entrusted with caring for you depend so much on their sight.

How can I help him when he gets like this? It is not easy to watch your child go through this. I felt helpless as I watched him sit there and bang on himself and throw himself around.
I feel helpless when he is yelling and banging. I feel helpless when I watch him run into people and things. I feel helpless when he spills his food everywhere. It doesn't feel like enough to understand why he does the things he does; why he relates to the world the way he does. I want to help him to be able to move through this world confident and comfortably. I don't like that he is hungry. I want to feed him but I don't know what or how.
