The first brand of sunscreen I ever used on my daughter's skin, was Tropitone. I bought it for our first family holiday, when she was only 7 months old. She has extremely sensitive skin, and she has had reactions to several lotions, but the Tropitone waterbabies sunscreen didn't irritate her delicate skin at all. The formula is quite thick, it's not a thin lotion, but it still absorbs well and doesn't leave the skin overly greasy. I use it on myself too, because I also have sensitive skin, and the water babies sunscreen doesn't contain any alcohol or fragrance, which is always a BIG plus in my books. It's a bit pricey, but you can't put a price on your little one's (or your own) skin. I highly reccommend this for every baby bag, and anyone with sensitive skin's hand bag, too. I carry a mini bottle full of Tropitone water babies SPF 40 sunscreen in my handbag at all times.
