Hi, I just thought I would pass on what I learned. My husband recently did a dermatology rotation and he asked the dermatologist what sun screen was best for babies. He said that it should say sun block, not sun screen and that it should have octinoxate and zinc oxide in it.
The ones I found that fit this were Aveno Baby and Disney Sun Pals Baby, by no add. Of course the no add stuff was much cheaper. It goes on a little greaser then the Aveno, but I thought it was fine.
