Best Sippy Cup: OXO Tot Transitions Straw Cup

A good sippy cup teaches baby to sip rather than suck. Oh, and it doesn't leak—but that part's for your sanity.

Somewhere between baby bottles and glasses, there's the sippy cup. A straw sippy is recommended over a valve one by the American Dental Association because it teaches baby to sip rather than suck and is better at cavity prevention. Here's the rub, though: Valves prevent leaks. We searched far and wide and found a sippy that put a valve in a straw.


  • Think straws are only for big kids? This sippy can be used for babies as young as 4 months old
  • The straw valve opens as soon as baby puts his or her mouth to the spout, so it’s easy to take a sip
  • The hinged cap creates a leak-proof seal
  • Use it with or without the handles, depending on what baby’s ready for. Plus, all the parts are dishwasher-safe


Recommended by dentists? Check. Leak-proof for parents? Check. Get this cup in baby’s hands—with or without the handles.

Price: $10
