My daughter is 5 years old and she has a birthmark on her right forearm . When she was a baby, it was just a tiny freckle . Now it is the size of a quarter, a little darker in color than a freckle, not perfectly round like a mole (irregular edges), and is now becoming just slightly raised above the skin. It s pretty much the same color throughout, maybe a few lighter areas in the mark. Do you think this is normal?
