@shell4life - Ouch, that sounds painful! I'm glad they sedated her.
I have a three-year-old with the same condition. I considered going ahead with the frenulum clipping before she has to start school and deal with teasing for her speech problem, but I have decided to wait.
Her doctor told me that sometimes the condition improves with age. I would hate to put her through something like that if I didn't have to, although I understand why your friend did. At five years old, her daughter already had to deal with social issues.
