When you say you don't see it going down, that's because it won't start going down yet, she's still a teeny bub.

I had a huge one, and I still had some of it when I was about 6/7, and even had an outline of it when I was very early twenties. It's gone now, but I was twenty a long time ago!

I was told that knocking it and bumping it was absolutely fine and actually increased the blood flow so was it was just business as usual.

I have not known anyone to have one removed, and I was surprised how common they are.
