Diaper bags — like purses and wallets — can be magnets for clutter. I speak from personal experience when I say that things go into them and rarely, if ever, come out. The smaller the bag, usually the easier it is to keep it clutter free and stuffed only with essentials.
I’m quite fond of the Pronto! Changing Station because it comes in fun, modern prints and it has a wrist strap for easy portability:
Small bags like this also can be slid into a larger bag, if you need food or blankets for a longer trip.
Fisher-Price makes a very similar product for about half the price, but without the wristlet and it is adorned with cartoon animals:
Both options are great for reducing the bulk and the clutter that plagues so many traditional diaper bags on the market.
