I am one of those evil parents who refuse to use the sunscreen because of all the chemicals in it. People give me the strangest looks when I tell them not to lube her up at school water play days. You would think I grew a pair of horns. Funny enough she never ever burns, even after being in the sun all day. That might be because her daddy is latin and she turns into a brown berry in the summer.
just be careful that burning is not the only form of sun damage -- there are lots of non-chemical sunblocks out there (those that use zinc or titanium as a physical block; they are not all like that chalky white stuff that we tend to associate with lifeguard's noses), and lots of people who never burn can end up with skin cancer. my stepfather, who was a non-sunburning geologist who did most of his field work in deserts, died years ago from melanoma, so it's an issue i've had some direct experience with.
