We got Brooklynn a scooter as a late birthday present from us. It's taken a little bit of learning, but she's getting better at it. She's almost to the point that she will glide a little in between pushes, which is an improvement from constantly dragging her foot on the ground when she first started.
She's also learned that it's much easier to go downhill and walk back up, especially when she gets someone else to push the scooter uphill for her.
And she always wears a helmet. And she usually wears shoes[1. I didn't have mine on this particular evening and so she refused to keep hers on either.].
