What will they think of next?

Laurel usually rides around in a baby wrap or carrier when we go out. Up until now, I've been tucking her inside my coat, and she stays nice and toasty warm. However, she's getting a little bigger now, so I've been thinking about either buying a bigger coat, or inventing some kind of cover to zip her into. Right now I rig up a cover with blankets, but that's kind of cumbersome. I don't like to dress her in a coat inside the wrap, because she gets too hot. I discovered that somebody already had this problem and invented a solution! The picture is of the Peekaru, which is basically a fleece vest designed to fit right over the baby carrier. How cool is that? Now, I'm trying to decide if it's worth the price tag.
