The Mystery of the missing Freckles

so KayLea has adorable freckles.. i'm sure she will probably loath them when she is older but they are just a sprinkling on her little face.. she is very fair skined so we are oh so careful and slather her with the heaviest duty sun screen but they still come through and we her whole life have called them Fairy Kisses.. we count them at the beginning of the summer until there are too many to count and then notice when they have all gone in the winter... KayLea will tell you her freckles fade in the winter because Fairy's don't like the cold but this year something kind of interesting has happened.. only half of her freckles have faded so far... my Mom seems to think it's probably because of what way she sleeps (although she's no wear near a window and even if she was she has curtains up) or where the sun hits her from where she sits in the car (again she sits in the middle so this theory doesn't really make much since either).. for what ever reason only half of her freckles have faded so far and here's KayLea's theory for now...
