How can I keep my child from getting a sunburn?
Keep your baby out of direct sunlight as much as possible, especially between 10 a.m. and 4 p.m., when the sun's rays are strongest. The best way to protect him is to routinely dress him in a hat and lightweight pants and a long-sleeved shirt for outings during the middle of the day. Add UV-protected sunglasses if he'll wear them.
Until August 1999, the American Academy of Pediatrics recommended against using any type of sunscreen on babies younger than 6 months. Their skin's ability to metabolize and excrete chemicals may not be fully developed. But the AAP now says that no evidence shows that using sunscreen on small areas of a baby's skin is harmful, and it's probably safe to use sunscreen on babies under 6 months if adequate clothing and shade aren't available. That doesn't mean you should slather your baby in sunblock, though. Just apply small amounts of lotion to his face and the back of his hands.
For all babies, the AAP recommends using brimmed hats and waterproof sunscreen. The AAP and American Academy of Dermatology recommend an SPF of at least 15, but many experts recommend 30 or higher for babies, and baby sunscreen formulas often have even higher SPFs. Apply sunscreen at least 20 minutes before sun exposure for it to seep in, and reapply it after your baby has played in the water, even if it's waterproof.
When trying a new sunscreen, do a patch test on your child's back to make sure he doesn't have a reaction to it. If he does develop a rash or redness at the test site, choose a hypoallergenic formula instead.
