I haven't gotten very far, but I have purchased my diaper bag. And boy, do I love it already.
Not only does it boast a removable changing pad that is cleverly concealed via an external zipper at the base of the bag, but it comes with a coordinating wipe case, reusable laundry bag and (just for fun) a matching coin purse. And I love that it looks like a purse and not a diaper bag. I had a difficult time choosing the color, but finally decided on the Buttercream Cake. I like the subtlety of the color and the beautiful pattern. It's admittedly a bit spendy, but I think that because it can also serve the role as a purse, it's worth the investment.
