My 7 year old dauther is very tan. I only apply sun screen when she is out for a long time (swimming, at a park, etc). She is in and out of the house alot durning the day, so it is impossible to keep sunscreen on her all the time. She has had a white patch on her forehead for several years, but I have noticed that she has about 5 spots on her this year. She doesn't get sunburnt. What can I do? Is it form the sun? Should I try to put sunscreen on her more often even though she is not getting burnt? Do I need to take her to our family doctor about these spots?
