There are a lot of choices when it comes to protecting baby from the sun. One I've been happy using for my boys, that is safe for babies and I'm certain I'll use for the baby this summer is MD Mom's Baby Silk Babysafe Sunscreen Towelettes. They're wipes, coated in sunscreen, so they go on easily--especially simple when you're getting your child dressed and there's no spray flying out. They're gentle, sweat-proof and have an SPF of 30+. Each towelette lasts throughout the wiping on a baby. And usually over a toddler or preschooler. To be safe, I usually use about 2 to 3 between both my boys. A set of 15 is perfect for a few days at the beach.
