Sun Protection and Babies
It used to be that sunscreen on infants 6 months old or younger wasn't recommended, but with the improvement of baby skin care products in recent years, the American Association of Pediatrics now says a little dab'll do your baby just fine, especially on those key body parts that are hard to cover, like the face, hands and feet. Just look for sun protection that's hypoallergenic and fragrance-free.
Generally speaking though, sunscreen is just one line of defense: Keeping babies' delicate skin protected with hats and lightweight clothing (and sunglasses, if your baby will actually keep them on) are always your best bet against the harmful ultraviolet rays, which are at their peak between the hours of 10 AM and 4 PM. And don't forget to keep your baby well-hydrated during those hot summer days.
