Interactive scanner plays music, lights, and sounds when play foods are scanned; volume is adjustable and batteries are included. The cart doubles as a stable push walker with Safety Resist Clickers to help toddlers build balance and confidence. Three adjustable heights (16.6, 18.8, 21.0 in) let the cart grow with your child and it rolls smoothly on hardwood, carpet, or other indoor surfaces. Six play-food shape sorters teach problem solving and shape recognition, and the roomy basket holds up to 10 pounds for toy storage or pretend groceries.
