Excellent addition to transform ride-on to a push-along stroller car! The Disney Princess 4-in-1 Ride-On features a push handle and safety shield around the seat for extra comfort and security, it will see children through all development stages. With four stages the Disney Princess 4-in-1 Ride-On can be used as a safety walker or rocker (with added curved board at the bottom) from 10 months, to go-as-you-please walker (with seat back handle) from 12 months, and finally to a fun-filled ride-on from 18 months and up.
