Five year old to have surgery next week. How to explain?

Our 5yo daughter has a inguinal hernia (look it up). Next week she is going in for surgery to fix the problem. The surgery itself shouldn't be a big deal, but she will be under general anesthetic (which is my biggest concern). There will also be some pain post-op. Aside from my own natural concerns as a parent, the wife and I are trying to figure out how to tell prepare her. She hates needles/shots, and we want to make sure she knows why she needs it. I'd feel pretty bad just sending her in there to get this procedure without any sort of explanation.Any tips on how to prepare a 5 year old for something like this?Side note, the surgery quote is over $40k and she won't even be there overnight. Insurance covers most of it, but the fact that something costs $40k for less than a half day's work is ridiculous. via /r/Parenting http://ift.tt/2igaxYM
