We have. Valentina wasn't 5 months old, I think she was 6 or 7. She had a few laser sessions in her eyelid/eyebrow hemangioma without anesthesia. she did fine. They used numbing cream on the area about 20 minutes before the procedure and held her down during the actual laser. She was upset that she was being held down but the laser itself lasted about 10 secs. I didn't want her to be put under GA for a 10 secs procedure.... I know for larger hemangiomas that require longre sessions it is sometimes necessary.
She cried afterward for about 2 minutes and then was perfectly fine.
