T.,
First of all, I'll be keeping you and your son in my thoughts - I know how difficult it is for you to see your baby go through something so traumatic. My baby girl had to have surgery when she was 2 days old, and I too was afraid about things like pain management, how long and hard her recovery would be, etc. I can give you a little bit of reassurance, though, that might ease your mind a little:
1. Doctors and surgeons take working on babies VERY seriously - they are keenly aware that babies can't tell you when they are in pain or scared, and in my experience they really go the extra mile to make sure your baby is comfortable and pain free. It's not like when adults have surgery at all!
2. Motrin really works for pain management in babies - I was doubtful that my daughter could have major surgery and all she would get was Motrin/Tylenol for the pain of recovery, but she never seemed uncomfortable or in pain at any time, which made me heave a huge sigh of relief. It did make her tired, though, and she slept alot.
3. Babies heal REALLY FAST! My daughter had a huge incision in her stomach 5 months ago, and you can barely even see a scar. It's amazing - your little boy will be up and running in no time and you'll look back and wonder what all the fuss was about:)
4. You can't feel guilty about doing something to fix a condition that will ultimately hurt his quality of life if you leave it! Believe me, he will thank you later when he can see clearly.
I know this is a tough time, and it will be so hard to give your baby over to a surgeon where you have no control over what happens and you cannot be there to comfort him, but you will get through it. Getting more information about the procedure itself might help ease your worries too - ask your doctor what the recovery will be like, when the stiches come out, how long before he can run around again, etc. so you feel like there are no surprises.
I'll be sending good thoughts your baby's way this week for a successful surgery and a speedy recovery!
