Who Invented These?

Who invented these little shopping carts?

I will tell you one thing they did not have kids? Claire has just discovered that they have these carts at Trader Joe's. If you try to sneak in without giving her one within five minutes an employee will bring one over. I hate them! It is hard enough to manage two kids and get my shopping done. It is really hard to shop, watch two kids, and make sure that Claire does not run into anything or anyone. By the end of the trip I am wiped out. I am sure of one thing the inventor of these did not have kids. Cute? Yes. Functional? No
