Let's walk, baby! The Puppy Walker is the perfect companion for your growing baby, offering interactive activities for babies who can already sit up and numerous encouraging expressions and support for those first steps. As little ones grow and start walking, the Smart Stages® learning content introduces the alphabet, shapes, colors, numbers, and even English words! Little muscles are exercised as babies who can already sit up reach for and interact with the activities, then stand up and walk behind the walker. Babies learn cause and effect activities as they discover how to activate the music and expressions by pressing the buttons or pushing the walker.
