My DS (11) is a VERY selective eater and has HUGE sensory issues and I just can't let it bother me anymore. He only eats one certain type of popcorn chicken; not kidding, one brand, anything else and he won't eat it. He also eats pizza, tacos, plain cheeseburgers, one style of macncheese (no boxed stuff) and ritz crackers. That's about it. Ocassionally he may have something else but rarely. He gets plenty as his weight is good maybe a little high. He gags and vomits at the drop of a hat and always has. He can see a glass of milk or a bag of doritos and loose it. I just put him in public school in January and he lost 15 pounds in 6 weeks (he needed to anyway) but he was not eating most days as he couldn't stand being in the lunch room. They were SUPPOSE to let him eat in another location away from the sights and smells but stopped after about the 1st week so it is now in his IEP that he must eat everyday (I send the same lunch every day) even if it means he goes to another room. I know how frustrating this can be. There is a sensory therapy that you can get now that uses a moving chair, music, and pink lights. I would have to research to get the exact name but I spoke with a woman whose son was like this and she went to Atlanta last year for the therapy and said it worked wonders on her son. He couldn't look at condiments before the therapy and after, he was eating them on his foods! Get the book and read it but your best bet would probably be to see a neurologist.
