This is a bit of an odd one, yesterday my DD had a black mark on her upper lip. We're in the middle of packing & she was drawing on a box with a sharpie (not for long) she also had a flyer that she chewed into small bits! Either of these could be the cause, the confusing bit is that I thought I'd washed most of it off last night.
This morning it was back plus a bit on her cheek too, I have tried to wash it off, it's faded but not gone. In the middle of the stain is a raw patch of skin, either from me scrubbing or what ever it is causing the mark. She's 2.5 & constantly sucks her fingers. I've checked her hands & the pen & flyer have been moved away. Any bright ideas?
