Yes !
Size: 0.47 Ounce (Pack of 1)
I order these every summer. My youngest is sensitive to sunscreens but this had always worked for him. The stick is handy when it comes time to re-apply and can stick in my purse for a quick trip to the park.

Great for running!
Size: 0.47 Ounce (Pack of 1)
This sunscreen does the job and does it well! It doesn’t smear or run and I didn’t experience any stinging around my eyes. Also, my face felt super soft after my 5K which was a nice bonus!

Easy Sun Protection for Wiggly Babies
Size: 0.47 Ounce (Pack of 1)
This product is easy to apply, even with a wiggly 10-month-old – which is saying something! Despite the challenge of a moving target, I will definitely purchase this again because it's a great applicator and provides excellent sun protection.

Gentle enough for my child to use on their own at school
Size: 0.47 Ounce (Pack of 1)
My child has been using this Aveeno sunscreen since they were a baby.👶 It’s always been gentle on their skin, and we’ve never had any issues with irritation or rashes. The texture is thick, more like a balm, so it doesn’t run or make a mess.Now that they’re older and going to school, I pack it in their backpack. The small jar is easy for them to open and apply by themselves before recess or outdoor activities. They usually put it on their face and arms, and it spreads easily without feeling sticky. I like that it’s not heavily scented and doesn’t leave a white film on their skin.❤️❤️❤️It’s been reliable over the years, and the size makes it easy to keep on hand.
