Little Shopping Carts

So I went to the grocery store a few days ago and as I am pushing my cart I happen to look over and this little boy is pushing his own cart...but it's so tiny! It has a little pole sticking up so that taller people will still be able to see it as they are walking around. It is so nice for the parents I am sure because while they are trying to grocery shop their kids can help too! And it keeps them occupied. What a great idea! What will they come up with next?
