E.F.
For everyday use I also use Burt's Bee's sunscreen and the special suits. But at the beach I switch to the 50+ sprays. The oil ones (not the lotion ones) are at least paraban-free.
I honestly wouldn't worry about some color-- burn is what you want to prevent. We've gone way to far the other way about sun exposure now and we're seeing kids with rickets... which is unbelievable. Some sun is good for her, and she will be one of the lucky kids who has both healthy skin and enough vitamin D....
You're doing great, Mama!
