B.,
This is such a concerning time for you! I know how confusing and strange the thought of your little one experiencing this can be. My son, at 6 mos. had an emergency circumsician (he was born preemie and couldn't do it at the NICU), and it was awful for me. Probably made it worse with all my worrying.
But, afterward my son had trouble calming down when he woke up from the anesthesia. They were supposed to come and get me before he woke up, and they didn't and he panicked. The nurse ended up having to give him demerol to calm him, so he could see I WAS there.
The surgery part went fine, it was the recovery time that was a bit tougher for us. Being a single Mom, I have had to learn when to ask for help. Keeping him comfy the first night, so he could sleep well was challenge, so he wouldn't roll over on his stitched area. I finally, had to ask my Mom to come help me and sleep in shifts. He had to be propped up so, he wouldn't roll over. After day two, it was a cake walk. We had a system down, and by the end of the first seven days he was healing and things were great.
But, otherwise my son was a total trooper and handled it like a champ. You could hardly tell he'd just had surgery.
I would ask questions at the hospital about procedures, and how they handle infant surgeries. Are you allowed to be there when they wake up...things like that. I didn't ask until the day of and wish I had been better prepared for the day of stuff.
If you can, enlist the help of friends and family for some support. Even if you can handle your little one, it's nice to have someone to help so you can take a shower with peace of mind.
Good LUCK to both of you!
