Hi there.. Also get club soda flatten it and make sure its room tempersture and have him drink it... It mimics the salt, baking soda, and water mixture suggested by CCCs it will help sooth and heal, and it's fully drinkable which the other mixture is not (will help the throat area). Also ask for a magic mouthwash prescription it is swallowable and will numb him so maybe he can drink his formulas - this will help maintain his swallowing reflex. Also there is a website called drink your meals.com it's run by a member of this site and is free to peg feeders and will give you home made recipes that are usable in tubes and will give the same or better health benefits. Take care and hope he feels better soon..
