LaurelHi Heather,
Our daughter was 15 months old when she had surgery and I realized we should have done it sooner. She was already way too mobile at that time and didn’t want to lay or sit still for more than 2 minutes. She pulled her catheter out several times trying to walk around and almost pulled some stitches out. I would think maybe having the surgery sooner (before baby can walk or crawl) might be an advantage.
I hope this helps. If you want you can e-mail me.
