Hi, My 4 years 9 months old daughter is having these marks on her legs (pic attached) which come and go randomly. We checked, she does not have any pain in them but sometimes they become dark and then fade away. Mostly I have noticed these spots to be more prominent and visible during the night time. She is an active child and eats well. However, her milk intake is quite less. Kindly suggest. The photo of the spots on the legs is attached. Kindly
