My husband and I often found ourselves rushing out the door with our infant daughter, whether on an errand or to the pediatrician -- I know some of you can relate! Apparently our communication wasn't the best, we each thought the other had the diaper bag. This resulted in us stopping at a store to purchase emergency diaper supplies during our outing. We found this product to be very helpful and saved us money in the long run. We each left one in our cars and always had an emergency supply of diaper gear (not to mention it's compact and convenient on those small changing tables)!! With our daughter now out of diapers, we converted it to keep spare clothes, snacks, and/or activities.
We're now expecting baby #2, and plan to start the process all over... hopefully preventing our previous parent fails.
I wanted to provide this tip!
