my daughter(2 1/2 yrs old) just went through her 9th eye surgery. I understand the stress and worry. Everything will be fine. I wish you and your family nothing but the best.
I got kidney stones my self (and I'm only 18), so I feel her pain...just on the other end...
Funny story. One time my mom told me if they can't come out, the doctors gotta stick a net up your pee hole to fish it out. At least they put you to sleep first.
Luckily, that's never happened to me, but don't worry...if it ever does, I'll post the pics.
