She's adorable! So, your surgery date is close! Our daughter had a scalp H removed back in sep. when she was 6 1/2 months old. It went well, she was such a trooper! I posted a new thread with before/after pics. Her's was ulcerated as well. We are pleased with the outcome besides some widening of scar tissue. Her hair will most likely cover most of it anyways.
Keep us posted on how surgery goes!
