Dd has just turned 4, and has a large brown birthmark that covers most of her right knee. It's just started to get hairy! Lots of downy pale hairs on it. I haven't gone to the Drs about it...it's just a birthmark and she is blissfully unconcerned about it, but I was wondering if anyone out there had experience of anything similar, as I'm sure she'll get acutely fussed about it later on...ie, is it safe to get the hairs removed? Best left? ( I'd clearly be leaving it for now, just trying to get clued up.) Ta
