Hi, S.! I'm sorry to hear about your son. My son was also 6 when he had his tonsils and adenoids removed. It's a horrible procedure, but trust me, you and your son will be happy when he gets the results of the procedure. It was more than a week of pretty rough pain. The key is getting him to drink, which he won't want to do, because it hurts. There is more pain at night, because he is sleeping and his throat dries out, but keep ice water by his bed and encourage him to drink if he wakes up... even though it really hurts. It tends to be a little worse on the 2nd and 3rd days, because scabs are forming and the healing process is really kicking in. It is horrible, but it will very slowly get better. What he is experiencing is normal. The pain is hard for a little boy to deal with, and it's hard to explain to them why it is so important to drink when they are in such pain. Give him anything cool/cold and wet. Like all the things you mentioned, I would also give him Jello, applesauce, pudding, anything cold and wet. I wish you and him a speedy recovery! I promise it will get better!
