I just bought a new diaper bag/purse. The pump bag that came with my Medela Freestyle is blah and not big enough to carry my other necessities. I got the Skip Hop Studio Diaper Bag and I plan to use it as a purse on work days and diaper bag when I'm out with LO. There's an antimicrobial pocket on it. It's a pretty big pocket, so I'd imagine it's not to just keep a pacifier clean. The description says it reduces odor-causing bacteria--so does that mean it's for dirty diapers/clothes?

Does your diaper bag have this pocket? What do you use it for?
