It's the baby's very own place to sit and discover new things. This magic ABC seat knows when baby sits, activating songs and phrases when baby stands. Press the light-up remote or flip book pages to hear numbers, shapes and more. Lift the cushion to reveal more fun surprises. The chair includes Smart Stages technology, an exciting new way to change learning content as the baby grows. Every baby develops at its own pace, and Smart Stages gives you the ability to select the stage that's best for your child.
