Playtime or in the Car! Children learn early to imitate what they see around them. It's an important part of early cognitive development and critical to balanced growth. Making connections to the real world through role playing also helps children accept change, assume responsibility and understand why they must do certain things. Joovy Just-Like-Mine! Toy Car Seat is fully compatible with the Joovy Toy Caboose Stroller (sold separately) just like the real thing! Joovy has developed the first doll car seat that helps children understand the importance of good passenger safety, without sacrificing play-time fun. Children learn to imitate the role of a caring and responsible parent as they safely secure a favorite doll or stuffed toy into the doll car seat. And parents find that their child is more cooperative about using their own car seat as a result!
