We've graduated from the point where I need to lug the gigantic diaper bag around everywhere we go, but we do still need to take a few things with us. On most of our outings, Wendy needs a sippy cup, a couple of diapers, and a small bag of Goldfish - not enough for a diaper bag but too much for a purse.
The perfect bag for me would be between the size of a purse and a typical diaper bag. It would be casual and neutral, so that I can use it 99.9% of the time without worrying about it matching. It should definitely have a zipper top, and a couple of extra pockets would come in handy. It must be under $25, because my eyebrow does weird twitchy things when I spend more than that on a bag.
Target is my store of choice for oh-so-many things, and this was no exception. I perused the clearance rack and found several almost-right options. Then I found this bag.

It's not perfect; it's a bit slouchy and blah for my usual taste, but everything else about it is good: price, size, zipper top, two big outside pockets & one little outside zippy for my phone. And it was $16.99, so no strange eyebrow twitchiness resulted from the purchase.
I'm not wholly committed to this bag; I'll use it until I find one that's just right, but that may take awhile.
Do you have a favorite bag?
