AN IMPORTANT NOTE ABOUT DIAPER BAGS FOR NEW PARENTS: You're supposed to fill diaper bags with CLEAN diapers. Repeat: CLEAN diapers. That is all.
Diaper bags are so much groovier now than they were 19 years ago. It seemed like they were all pastel colors & sissy. I finally settled on a denim one.
As the mother of twins, I found typical diaper bags pretty useless. They were too small and generally not that well made. I used an LL Bean bookpack - plenty of room and it never failed me. But then, this was 8-9 years ago, things might be different now.
