Does anyone know if siblings are likely to share this birthmark? My 2.5 year old was diagnosed with this shortly after birth and has received laser treatments. I just had a baby boy last week and I am noticing a blotchy red cluster of veins on his eyelid. It is not raised at this point but who knows. I am starting to panic. I really don't want to go through this again. People were so insensitive with my daughter - What's that on her face?-asked daily and the expence of treatment-not covered by insurance. Please let me know if anyone has any information. Chris
