The OXO Tot Sippy Cup collection offers several spillproof solutions for teaching baby how to drink like a big kid. The larger capacity of the 11-ounce Sippy Cup makes it ideal for sipping at home or on the go. All Sippy Cups have non-slip grips, a dimple in the lid that makes room for little noses, and clear walls to show just how much is left. Each has a leakproof valve which releases pressure for comfortable sipping and is easily removable for cleaning. All OXO Tot Sippy, Straw and Training Cup lids are interchangeable.
