DD (8) is a twin has a large epidermal neavus birth mark on her tummy - a continuous line about 6 inches long and in an arch, raised and light brown. See pic for something similar. To make sure she isn't self conscious, we call it her shooting star. In the last week however I have started to find additional birth marks on her torso (back, under arms, tummy etc) which were not there before - they have the same raised bumpy feature. I will book a doctors appointment but feel quite concerned, hope it doesn't move to her face. Anyone come across this and could provide some wise words, thank you x
