We use the Banana Boat Babies. It has Zinc Oxide and Titanium Dioxide with are "sunblocks" not "sunscreens". They start protecting imediately whereas the sunscreens dont start for 20-30 minutes after the application. Also, it is what our pediatrition recommended. They have worked very well for us. We have also tried the Avon sunscreen with the bug guard in it. Great for the outdoor adventures and you only have to lather them once. But I dont think I would use this on an infant.
