Our answer to the question has changed as baby has grown. Our look inside readers' homes as part of AT: The Nursery's Smallest, Coolest contest has got us curious about what everyone is carrying in their diaper bags.
Right now if you looked inside our diaper bag/purse, you'd find:
diapers, wipes, small changing pad, diaper rash ointment
onesie and pants
bottles, ice packs, baby food, disposable bib, sippy cup, spoons
small bottle of hand sanitizer (since confiscated by TSA)
wallet, keys, cell phone, blackberry
Share with everyone what's in your diaper bag. Are you a minimalist or do you pack for every contingency? Let us know if you've got a great tip for packing and organizing your bag.
