I was just thinking about our past discussions on here about sunscreens.
This is a tough one for me. Everyone in my family is very fair, although my ds and I do not burn. I joke that I'm so white that I reflect the sun :P If I spend a lot of time outdoors, I become olive-toned, but it takes a LOT of sun. My dd and dh are much more sensitive to the sun and burn easily. My dh can get a burn from sitting in a car, and my dd has burned under a shady tree on a cloudy cold day in February while inside a sling (completely covered)!
We spend a lot of time outdoors year-round, including snow sports which are so risky for sun exposure. Not only is the snow reflecting the sun back at you, but we are usually at an altitude around 12,000 ft., so there is very little natural protection up that high. We have only found one brand that doesn't break my kiddos out in hives, and it is not natural, so I try to use it very sparingly and only if I absolutely must.
I don't know... It is such a tough call. Neither option is perfect. Cancer runs in dh's family, which makes me concerned both for the ingredients and the sun exposure
