My doctor recommended neutrogena baby. All the reviews have said its the most gentle sunscreen out there and even people allergic to sunscreen are able to use it.
I've never seen it in stores, I order from Amazon. It's pricey, but so worth it. I love this stuff. For baby I get the sensitive. I've been using it at my pedi and dermatologists' recommendations since DS1 was born and this stuff is awesome. I use it myself (I have sensitive skin).
