Congratulations on your new born baby! My son is 18 months and he was born with a port wine stain or Klippel-Trenaunay Syndrome. He has the birth mark on his left arm, shoulder and back and part of his neck. Since he was 2 months old his been getting the laser treatment every-other month. We have seen the difference, the birth mark is much lighter. This doctor is one of the best, you can visit his web-site and even call him. He will help answer your questions.
