The Baby Amaze 3-in-1 Care and Learn Stroller by VTech has three fun ways to play and learn with your baby doll! Place the included baby doll in the stroller and go on a pretend walk. The stroller’s smart sensor recognizes when it’s being moved and plays sing-along songs about letters, colors, places and animals. Transform the stroller into a high chair to hear baby care reminders that introduce nurturing concepts and healthy habits while you pretend to feed your doll. Turn the book’s page on the tray to learn about different foods and nutrition. Transform the high chair into a bassinet, and your doll can fall asleep while listening to classic nursery rhymes or 20 familiar lullabies. The 3-in-1 Care and Learn Stroller also has number keys that introduce numbers and counting and plays piano sounds in music mode. With three ways to play, this stroller is packed with role-play fun! Requires 2 AA batteries (batteries included for demo purposes only; new batteries recommended for regular use). Intended for ages 2 to 5 years.
