My daughter had a friend when she was younger that was legally blind, you could tell her eyes were both too small. She had a walking stick to help her but I swear it never slowed her down, I am pretty sure she could still see well enough to play, I never had to assist her when she came over. I run into her mom in the supermarket every now and then and her daughter has since had some surgeory that has helped. She is now a teen and giving her mom hell like any other teen

Edit to say...I am really sorry that you and your husband are going through this worrying, there is nothing worse...I never knew what the worry of having kids would be till I had them, get use to it you will worry about 5 million different things through his childhood.
