This cart might be nice if my 18 month old was taller.  It is too tall for him and hard to push, so he really doesn't play with it.  I don't like how it doesn't really resemble an actual shopping card (the yellow part of the design seems weird to me), but maybe that makes it more stable??  My biggest problem is the height though.  My son is just under the 50% for height, and it is too tall for him.  By a lot it seems.  Unless this is really targeted for 3-4 year olds, it seems like they could stand to make the cart shorter.
