my grandson got his tonsils out yesterday, and is still quite ill

I had my tonsils out when I was 13. It was not a pleasant experience. I remember loosing weight because I couldn't eat solid foods for a while I just didn't feel like it at all. It was summer and hot and humid so one reason I probably didn't want to eat. Give him lots of soft food like popsicles, jello, pudding, ice cream, apple sauce, soup, mashed potatoes. Just let him watch Tv or play games because he probably won't even feel like talking much either.
