I just went through that with Sophie, Her surgery started at 2 pm, at 5 she was ready to be picked up, I thought she was going to be asleep, but she was awake all the way till we got home. She did not need pain medication and before 24 hrs. I had to be careful, trying to keep her from jumping on and off the furniture. She didn't get stitches, not in the outside, only inside, and just like everyone told me was tougher on me than it was on her.
Sending a big hug to you and your baby, she'll be fine, and so will you
