S.B.
there are a lot of good books to help kids through surgery.
GETTING YOUR CHILD READY FOR OUTPATIENT SURGERY by Jerry C. Vaughan (Paperback - Jul 1, 2004)
Will It Hurt? Parent's Practical Guide to Children's Surgery by MD (Dr. Ketch) Armen G. Ketchedjian (Paperback - May 1, 2008)
these are just a couple of choices I found on Amazon.
My son had an undescended testicle fixed and I'm guessing you're talking about something like that. We talked about how he would go to sleep before the surgery and wake up afterwards. I would be there with him when he woke up. He would have a bandage to cover the wound and stitches and he couldn't touch it or scratch it. It would be on his skin a few inches away from his genitals and would heal in a few weeks. It would only hurt for a couple of days and he could have medicine and ice cream and candy and Legos and watch TV while he was healing.
He was very cranky when he woke up from the surgery and wanted to get out of bed and go home. It was kind of funny actually. He had only a little pain and was easily distracted with treats and toys. He went back to school in just a few days. He kept the cute little slipper socks they put on him before the surgery and wore them for weeks - he loved having a souvenir.
take care, S.
