My DS who is 8yrs old had his tonsils and adenoids taken out earlier this year. We went through a public hospital and ENT. His surgery went fine and DS recovered quickly.
ETA: DS ate dinner at the hospital a couple hours after the procedure but wasnt interested in breakfast the next day. The nurses refused to let him leave until he ate some breakfast so he forced a bit of toast down. We bought him one of those variety packs of (sugar filled) cereal and let him eat those whenever he wanted. It was half crunchy, half soft and the cool milk felt nice (apparently). We ate normal dinners but made his favourite (baked salmon) which was soft, but he had normal side dishes so he was keeping his wounds clean. He swallowed 'a lump' in hospital and absolutely freaked out.....FREAKED OUT....had to be sedated the 'lump' was a bit of the scab and it just frightened him.
Looking at him now, its amazing how much the procedure helped him though. He used to rattle the windows at night when he snored and couldnt breathe properly...now he sleeps with his mouth shut and breathes easily through his nose
