Open Question: 8 year old is having her tonsils & adenoids removed & getting tubes in her ears. I'm worried about recovery!?

What kind of recovery should I expect? Dr. said a sore throat & she will miss a week of school (not a big deal). I have read of quite a few kids being down & out, having the worst sore throat you can imagine, not eating & being on codine for pain. This is making me second guess the Dr. for down playing the recovery & I am thinking I need a 2nd opinion??? ANY help would be very appreciated. Thanks!
