When we first had children, all sunscreens seemed potentially lethal. Then we discovered California Baby, which is still our go-to sun protection lotion now that the kids survived the toddler age. (Selma Blair is reportedly a fan of the brand.) This organic, sustainably grown, allergy-tested line isn't on the cheap side, but you'll feel good putting it on your wee ones because it's PABA-free, non-chemical, fragrance-free, water-resistant and hypoallergenic. Its main ingredient is micronized titanium dioxide. Our favorite is the easy-application sunblock stick, which is perfect for feisty small faces wiggling away from Mom's fiddling fingers, and thick enough not to wash off easily.
SPF: 30 Main ingredient: Micronized titanium dioxide Price: $14 for 0.5 oz.
