Hi there I have a daughter who is 3 and a half, I recently realised she has a brown spot like thing on her stomach it is slightly raised on one side, I read up and seems to be a mole, it isn't a full circle it's more like an oval but it isn't exactly that shape, please advise as I am very worried, she has had it for some time I can't really remember how long but it only got my attention today.
