Great info. I have noticed that my tolerance to sun exposure has gotten better since I've started taking high doses of omega fats and vit d3. We rarely use sunscreen around here either. I have a full body swimsuit for Olivine when we're going to be outside for a long time.
Yeah, I mostly just put Mirabel in a UV suit and WIDE-brimmed hat. We are all extremely fair over here though (I'm blonde and pale and DH is a redhead), so some barrier sunscreen gets used occasionally. I also have those mesh sun-barrier BabyLegs, which are great putting on while baby's in the Ergo. But this is also the Canadian Pacific Northwest, so our season of hot sunny days is very short.
About Badger sunscreen - I just bought the baby stuff (have usually bought the lavender, but didn't want to use lavender on my boy) and it's all... chunky? Grainy? Like little solid bits that look like bits of white cornmeal or something. And they do rub in eventually, but not easily. I'm turned off by that. Has anyone else experienced this?
