Earlier, I noticed my daughter's hands were bright red. No sign of like a rash or flaky skin and they weren't cold, I rubbed them just in case and they went white.
But seconds later they went back to red.
I had her hold her hands above her head, and when she lowered them they looked normal... Complete with filthy 8 year olds nails.
So I took a photo, one hand is red, the other white after I've rubbed it.
It's like pushing blood out and then it fills back up again iyswim.
