I am notorious for not wanting to tote a bulky diaper bag everywhere, so sometimes I just throw a diaper and some wipes in the bottom of the stroller when I am running in somewhere. Apparently, the folks at BePe Baby are right there with me, because as I was browsing their site I noticed this very cool Diaper Roll Up that I swear was invented for me! It has room for 4 diapers, a tube of diaper rash cream, and a hard plastic case of wipes. Then you can just throw it in the bottom of the stroller and know you have everything that you need in one place! Diaper Roll Up, $18 at BePe Baby.
