Does anyone know if some children on the spectrum are always craving food like something sensory? I had my child tested for PWS it was bloodwork which came back normal but he acts as if he's always starving and will actually eat all day and keep eating until he has a BM. Then eat some more and have more BM's. He eats everything and anything and even school always tells me how he wants to eat all the time. Seems as if that is all he talks about too though he doesnt talk too much. He demands food and has since he was younger. Iron was checked and normal and his weight is fine and if he could get in the cupboard everything would be gone. He gets very very angry when someone isnt giving him food alll day. I have other kids to take care of and he gets sets off cause though he already has eaten hes angry cause i feed them.. I am at a loss how to help him he cant possible eat all day literally.
Is your child able to follow routines well? if so, maybe creating a picture card routine scheduling in eating times. perhaps he feels that he needs to use his bowels and has worked out that eating does it? if you've looked into medical reasons for this habit (which it sounds like you have) then it is likely behavioral and you can look into that. i found when working with children and teenagers with autism eating was a big issue, as was related BM. using the bowels can become a stimulatory behavior and as mentioned already, this might be related to his food intake. just my opinion and experience but i hope it helps a little. you could also talk to a behavioral consultant specialising in autism and they may be able to give you some tips too. i found with one particular child that routine was crucial to his food intake and setting limits. we started scheduling in food times very regularly, close to his previous habits and then slowly reducing them and replacing these times with something positive, such as reading a book, going for a walk, leaf scruntching, playing with jelly, etc. good luck!
My 6 year old is exactly the same. We tried turning him on to water. He always wants something in his mouth. Now he grabs water for himself. I let him have breakfast, two 1/2 lunches to spread out his intake (that works wonders), dinner, and a snack at night. Since he now loves water, he has that instead of eating 24/7. Just make sure, if you try this, that he isn't drinking tons
My grandson would eat all day long and will not drink water but while remembering that his therapist had shown us that by giving him something sour he became calmer. So, that is now what we give him and he will pack a pickle around and not keep opening the refergerator.
Not sure where your son falls under the spectrum, but my guess would be sensory or stemming. If you have visited your Dr. and all is well, I wouldn't worry too much. Sounds like you may have to replace the behavior with something else. Good luck!
