What about using a wagon? If you are going on walks in your neighborhood, a wagon is a great item for multiple uses... the kids enjoy the wagon, also. Just be sure to get one where the front wheels turn easily.... the OLD one we have has the front wheels on a pivot with the handle, so when I turn the handle, they turn also. The big plastic one from Little Tikes the wheels turn independently, and the handle is not on a swivel, so it really is a pain to turn easily. Try a couple out if you can.
