Every Mom I know seems to be in search of the perfect diaper bag. It probably doesn't exist, but this one comes close.
There are several designs (including prince/princess, heart, and peace). What I thought was cool was that the strap is designed to fit around a stroller or on your shoulder. There is a pocket for a baby bottle and your water bottle plus one for your cell phone. It includes a changing pad. It isn't cheap, but what is. These will set you back almost $100 plus shipping.
