The OXO Tot Sippy Cup collection offers several spillproof solutions for teaching baby how to drink like a big kid. Available with handles, the 7-ounce Sippy Cup is easy for little hands to hold when baby is transitioning from a bottle. The Sippy Cup with Handles has soft, non-slip Handles that are angled so baby doesn't have to turn his wrists too far; the Handles are removable for when baby’s grasp develops. All Sippy Cups have non-slip grips, a dimple in the lid that makes room for little noses, and translucent 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.
