Bimba

As far as I know, the English language does not have a word specifically for those little baby push-carts that help new walkers hone their ambulatory skills. I have learned from O., a friend of mine from high school, that in Israel they are called "bimba", so that is what I now call them as well. Check out O.'s lovely family and the bimba fleet on this post of his blog (which, incidentally, was the inspiration for this blog) at http://mikedonch.blogspot.com/2008/03/park-hayarkon.html
We got a bimba for Supergirl, and it was an immediate hit--great for cruising around the the middle of the room ON FOOT!!! and even greater for plowing into any mountains of unfamiliar objects one might happen to encounter.
