What a beautiful boy you have!
Our daughter has had an ulcer since july :-(
I donīt have any suggestions for you other than keep an eye of any eventual infections. She has had two rounds of penicillin so far.
About the grey in the middle, our doctor here in Sweden says that it could involute in the middle, but as long as the edges are red, the hemangioma is still active. Is it warm? It is also active as long as it is warm according to her.
I keep my fingers for your boy that he will not have a big ulcer!!!!
