I saw a video. One of those (cough) funny videos. A baby, somewhere between one and two, was in their little rolly seat. There probably is a proper name for those. He had on tiny running shoes, and he was running. I mean RUNNING down the street.
I need one of those.
The problem with a walker is that it's in front of you, with wheels, that keep moving. It's really hard going downhill. On a scooter, or in a chair your feet aren't on the ground. But one of those rolly chairs would be perfect. The seat would be right under you. The wheels would be all around you. You'd have a little tray. Perfect.
Downhill might still be rough.
