The VTech On-the-Moove Activity Bar is a cute farm-themed toy bar for babies on the go! Press the button on the cow, and be rewarded with cheerful phrases and playful songs and melodies. Swing the cow back and forth to activate the motion sensor and hear interesting sounds. The bird holds a textured ring that’s easy to grab, and the ladybug has a baby-safe mirror for peek-a-boo fun! This interactive bar easily attaches to most infant carriers using easy to attach adjustable elastic straps. The baby activity bar is intended for babies from birth to 3 years. The musical toy requires 2 AAA batteries (batteries included for demo purposes only; new batteries recommended for regular use).
