DS has a throat infection and ulcers in his mouth and down his throat, he obviously doesn't want to eat anything or drink, I am managing to coax him into drinking just enough to avoid being dehydrated i think. But he is starving and desperate to eat something, I have tried everything from ice cream to mashed up weetabix and everytime it touches his mouth he screams in pain and then gets more and more upset as he can't eat and really wants to. It has now been about 5 days of totally minimal food intake, yesterday all he had was a some porridge. How long do you think he can go with no food and has anyone else been in this position?
