My son Nicholas' h. looked very similar, but grew rapidly at 2-6 weeks... he was put on oral steroids and we then started laser at about 4.5 months old.
If you would like to see pictures of my son, go to www.multiply.com
(you probably have to register to see pictures, but I will approve you)... he is on the last album, under Nicholas' segmental h. Our first priority was his eye as the h. was in is upper inner eye lid and it was causing drooping. Our second concern was the damage the h. was doing to the skin, and skull as it the h. became very thick. Laser in my opinion kept his skin firm and reduced the red. Another issue was the telangiectasia vessels (your daughter appears to have this as well) were quite thick and there were a lot of them. His doctor actually traced each vessel with a diode laser to destroy them. We could not be happier with the results. If you would like to know more, feel free to email me
