J.S.
My daughter used to snore and had sleep apnea from birth until she had her t&a taken out at 3 1/2.
The surgery was about 30 minutes and her recovery went great (once I got her home). I took her home from the hospital the day of the surgery, she slept for a few hours, woke up and asked for a grilled cheese sandwich lol. We actually went to the park for a couple hours the next day.
My suggestions would be;
1. do NOT let them give her a seditive before the surgery. The nurse told me after my daughter woke up that most kids become angry/violent from it (it would have been helpful to know that before I let them give it to her).
2. Explain to your daughter that she will wake up with an IV in her arm. I didn't think to do that and mine freaked when she woke up.
3. Insist that they let you back in the waiting area BEFORE they bring your daughter back there so you are the first one she see's when she gets up. They told me they would do that and didn't.
She will sleep so much better and you will both be happier after the surgery is done. Good luck.
