Imsotired/samj - my LOs surgery I had a few days to process the information but was still sobbing all night with him in the hospital. It's so frightening to have the LOs go under, but the risk is so so low now. The hardest part is handing them over to the surgical team because my LO was so small, only five weeks, I literally had to put him in the nurses arms. It was hard, but it was over so quick and then he was back with me (and ready to EAT!). just know they will be a little groggy coming out of the anesthesia, which would have scared me had my mom not prepared me for that.
Just find the best doctors you can, thankfully we live near a very good children's hospital and had the surgeon our ped recommended. Recovery for my LO was easy, his cries were just a little hoarse from being incubated. Make sure you have family or friends to be with you during the procedure. My mom, DH, and I went to the hospital cafeteria to (try to) eat and chatted about other things so I didn't spend the entire time watching the clock.
Now it is just a distant memory and LO is so perfect, barely a scar because their young skin heals so quick. The hospital gave him a little stuffed dr bear, we told him no more of those! There's a 40% chance he can develop a hernia on the other side and need surgery again. So far there's no evidence of one.
