Our son has many raised ones in his diaper area and 1 (size of a quarter) that is in between the cheeks of his backside near his rectum. Pooping used to cause it to ulcerate and bleed daily. We found that using topical propranalol 2x per day has eliminated ulceration and bleeding. Even in the heat, when he gets a mild diaper rash, the hemangioma doesn't bleed.
I know it isn't exactly the same location as your daughters but maybe it is something you could look into. Took about 3 days before we noticed improvement.
