Out of the 11 foolish ways this guy thinks we spoil our kids, we only ever used the shopping cart thingy, and that was only because it was winter and most of the carts were really cold when we got them. Now trying to plunk Olivia in the front seat results in a class-3 meltdown, so we normally just plunk her in the front and make a lame joke about markdowns and warranties to the checkout person when we're done.
That diamond binkie though, that's something I'm sure she'd be all about. Little girl definitely likes her bling already.
