With my first dd, I used the coppertone waterbabies one. She never had a reaction to it, and never burned. However, she doesn't have sensitive skin when it comes to products, and she also has a little darker skin from my side of the family. She has never had a sunburn. I made sure to put it on her head also, because she hated wearing hats, and was always pulling them off. With my 8 month old now, I think I'm going to try something else.
