What a cutie! I am glad you were able to get early intervention. I am sure everything will go fine during surgery. My daughter Valentina (now 16 months old) has been through 2 surgeries and 4 GAs total so far and every time I was a nerve wreck, but she did wonderful. In her case, after her first surgery the hemangioma grew right back, but this happened because 1) the H was only partially removed and 2) she had just come out of 9 months of steroids right before surgery so this was probably rebound growth. The second time they removed he entire H and so far so good. You can see her story at http://www.youtube.com/watch?v=LSXQIwdeoVQ
Good luck with surgery and we'll be thinking about you!
