Let me explain...
Right now my world revolves around 3 guys...whom I love dearly. However, without certain items packed into my diaper "backpack" we could never go anywhere. (Well, I guess we could but it wouldn't be pretty.:)
See exhibit A:
No, its not the cutest diaper bag you've ever seen, in fact most would think its ugly. But I'm all about practical. I can hold the hand of a 4 year old, cell phone, a full church bag, and a haul a carseat all in one trip with this thing on my back.
Some of my other bags...
Here's my "stuff everything I possibly can into it to so I can galavant around Europe" backpack. Not pretty, but definitely useful.

Sometimes you can find my bag on my back...
on my front...
over my shoulder...

by my side...

or around my waist.

I love when others carry it.

At times I need more than 1 bag...

Or none at all.

And other times they just sit by me while I enjoy the moment.
