My gran daughter was bron with white patches on her legs and a white spot with white hair coming out of it on the tip of her bang sight. She is two now and the white spot of hair has shrunk, or else its just that she has grown and now you don t notice it much. However her legs are very noticeable. They are from low thigh to shin bilaterally. Is this a disease that will progress? Or will it stay the same? Her mom also had two whit spots on her legs but they are 1/2 dollar size and haven t changed in size. Her grandfather had an inch of white hair in the same spot as my grand daughter that never changed either.
