24 Essentials For Traveling With a Toddler, From a Mom Who's Done It

Built 12oz Wide Mouth Cascade Bottle ($15)

I've tested out many water bottles for my son, and most end up leaking. The Built bottle is the best one I've found. The lid is threaded so it screws on tightly and doesn't leak, even when left on its side. It's PVC-, BPA-, latex-, and phthalate-free, and the 12 oz. size is perfect for a toddler's hands. I love the bright-red color that makes it easy to spot.
