Best Baby Sunscreen ☀️
Size: 6 Ounce (Pack of 2), Style: SPF 50 Spray
Putting sunscreen on a one year old is never an easy task. So I learned very quickly that the spray was a must. I’ve tried several different kinds and have had issues with eye irritation because I’m sure as y’all all know (that I definitely did not know) the first thing they do when you put sunscreen on their face is rub it immediately in their eyes. Although this one is not completely irritation free, I have noticed much less irritation to her eyes (or maybe she’s finally learning not to rub her eyes after I put it on idk 🤷🏼‍♀️). Regardless this is a great safe, easy to apply sunscreen for babies!

Thick & Protective
Size: 6 Ounce (Pack of 2), Style: SPF 50 Spray
I like this spray because it goes on thick and stays on for a while (even when playing in water). It does spray on white and requires a quick rub in, but I know my kids are protected from the sun when using this product.

Problem with the sprayer
Size: 6 Ounce (Pack of 1), Style: SPF 50 Spray
Great scent, feels soft after it's put on, but the spray is defective. I don't know if it's just this bottle or the lot, or a manufacturing issue overall, but the spray comes out fine initially and then doesn't, getting clogged temporarily till you stop using it for a while. Then it works fine again. Otherwise I would not have a problem buying it again, if I know it's just a one-off situation with this particular bottle.
