Clean & Simple Sport Bottle by The First Years

If you're looking for a cup that won't leak, this is the one. Toddlers love the cool, sports bottle look, and parents will like the flip-cap that keeps the mouth of the bottle clean.

Pros

Cons

I was skeptical about the built-in valve on this spill-proof sports bottle / sippy cup when I first saw it. After using the cup, though, I was impressed. This sippy cup leaks far less than any other sippy cup I have tried for my daughter, but she has no trouble drinking from it. Finally, a winning combination! The built-in valve not only means you won't lose the valve, it's easier to clean, as well. There are no crevices in the valve to trap juice and germs or grow mold when the cup takes a long vacation behind the couch. The First Years Clean & Simple Sports Bottles at our house have stood up to repeated dishwasher cycles and still are spill-proof and in good shape. The caps still fit tightly and there are no visible signs of deterioration. Best of all, my daughter loves these sports bottles, because she doesn't see them as a "baby sippy cup." The cup passed my best attempts to spill without leaking - I shook it upside down, side to side, and left it upside down in a bag - and it barely leaked in any of these tests. The First Years Clean & Simple Spill-Proof Sports Bottle is a winner for babies 18 months and up!
