A.,
Best bet will be to go with something as safe as possible, thus eliminating many of the harmful ingredients that are typically found in many sunscreens and blocks today, even baby ones.
Here's a great site that give you a rating for personal care products and also gives you a list of ingredients. I would strongly recommend anything listed with a score of 1.

Arbonne was not rated, but I do know that their products are wonderful. I have used many of their baby products before.
Aveeno as a whole is a great line. However their sunscreen I would be cautious about using

Hoping you find what you need.
