L.M.
We went through this when my daughter was about 18 months. I was upset, because it was identified when she was a baby and they said they would "keep an eye on it." Well, it never got better, so at 18 months we had to go to a Pediatric Surgeon to get it clipped. The PS told us that if we had it done when she was an infant, they could have done it in the office with a quick clip and she would not need "surgery" with anestesia. Well, she was so scared, there was no way the PS would have been able to safely cut it without anestesia. I think they used a scalpel, not laser.
But I digress....
We had it done and it was no big deal. She ate popsicles for a day and was good to go. I guess there are not a lot of nerve endings there so the pain is minimal. Because we got it done before her speech really started, there was no issue there.
