A. Hello ma’am Had it been there Is is the chai time your child is born because certain times kids do have a birthmark like this and it happens the same way it becomes a little more during the sun time and indoors it is light so if this is the case it could be a different story but other than that whatever it is it would be better that you consult your paediatrician for a proper checkup once on
