I use mine for my essential things like credit cards, money, license,cell phone etc. This way I can just take it out of my bag for short trips to the store and not have to take the whole bag so basically everything I "need" is in there for trips without the kids. I have since developed a method for that too. So I always spend so much time packing for the kids so I never get out of the house in time for fear that I may forget something. I know this is OT but somehow ties in so I got 3 bins for my car. 2 for the floor of each carseat so in front of each carseat and one in the back. Each child has their own bin for diapers,change of clothing, snacks,toys,books,extra toothbrush,wipes,etc. gloves and hats. then in the back bin in the hatch part of the suv is stuff if we ever get stuck in a ditch lol non perishable food,extra toothbrushes,firstaid kit (i have 2 in the car) blankets,water,vinyl disposable gloves,saline, isopopryl alcohol) I know I am a freak but anyway, having all of this stuff in my car in an organized system allows me to feel more comfortable with just having to bring my wristlet when I leave the house. I am trying to get more organized but my classic front pocket turnlock leather wristlet was my first coach and I used it way before I started buying bags.
