This Melissa & Doug K's Kids pull-and-go vehicle set is designed for children ages 9 months and up. The set includes four soft, lightweight vehicles: a dump truck, mixer, loader, and crane. Each piece is easy for young children to grasp, lift, and roll. As part of the K's Kids line, these toys are developed to support cognitive, physical, and social skill development in early childhood. The soft construction makes them safe and manageable for small hands.
