my daughter (19 mos) had a forehead H a little lower and a little bigger than this...we elected to have surgery when she was 12 mos and for us it was the best decision. scar practically invisible 7 months later...it is just below her hairline, and i even decided to grow out her bangs as there's nothing to hide anymore. here are some pictures,
including right before and right after surgery. most recent is i think in june, so 6 months post op.
