With all the resources out there these days on what to buy kids, we find the best source is usually the mom next to you. What sunscreen to buy? What rashguards your kids will wear? What hat will stay on? Moms have tested it and know! We asked the designers (and moms!) behind the brands on tada! shop and our distinguished moms board "what is the one thing you cannot live without this summer for your kids?" These women are from all over the country with children of all ages and have that great eye! How fun to see their answers (and we had to weigh in too!). From "don't know how I had the time before it" Fresh Direct grocery delivery to the Liberty for Target bathing suit that "was the 'outfit' for her birthday party" to the give-the-dvd-player-break travel game or the "live-in-all-summer" kurtas and bloomers. Oh, and why not serve "coconut water as a fun BBQ beverage choice in tumblers over ice!" SHOP THE ESSENTIALS >
