Protect: Green Beaver spray on sunscreen for adults and kids/Aveeno Baby sunscreen stick
Swim: Distinctly Home beach towel/Banz swim suits
Sit: Skip Hop Central Park Blanket
Snack: Nature's Path Organic Kamut Puffs/foogo sippy cups/Kleen Kanteen/mixed nuts (I get mine from Healthy Planet)
Well we're right into park season here in these parts and I always have a bag ready by the door with all of the essentials. I finally found some sunscreen I love that's environmently-friendly, in a spray bottle and not greasy. If you've never tried the face stick, check it out. Leo loves putting it on his face as well as the patio door and for some reason the kids don't squirm as much when I'm applying it.
Most of the parks in our area have splash pads now (yay!) so swimming gear is a must. Both Leo and Mila have Banz bathing suits, which I love because of the protection factor and of course beach towels are a must. I also bring a waterproof park blanket with me so we can sit to have snacks or a picnic lunch.
And speaking of eating, both of the kids are obsessed with these kamut puffs. They are baby crack and contain no sugar - like zero - so I don't mind if they eat them all day. I also always have a little container of mixed nuts either in the bag or the stroller so I don't get famished (Leo loves these as a snack too) and all of us drink from these stainless steel containers (well Mila is still getting the hang of it - mostly she throws it on the ground).
That's it! What are your park essentials?
ps - these are all things I own and are my opinions only.
