mommy clutch by Lilly Bit that will serve as the diaper bag. Wet/dry bags have pockets for both soiled and unsoiled items. For longer days out, I will bring a larger wet/dry diaper bag, like the bag or backpack I registered for on Amazon, both by Planet Wise. I intend to sew in velcro in the backpack so that the wet pocket will velcro closed to help prevent smells and leaks from escaping. I also purchased a wet/dry bag with clear pockets on the outside by Smitten Baby from babyhalfoff.com because I liked the idea of having pockets that would allow me to see where things are. However, the pockets only have one piece of velcro in the middle for the closure, so I may sew some more velcro on so that the pocket closes more.
Don't forget to have a nice changing pad, too! I registered for Kushies Deluxe Flannel Changing Pad because they're extra large, soft on one side, and waterproof on the other. If you have a crossover, SUV, or van, you might also like the car changing pad by Dipe n' Go. It attaches to the inside back of your car, holds diapers wipes, and keeps the pad in place since it's being held in down. I've also found a couple diaper rash ointment options that allow you to not get gunk all over your hands! Wouldn't that be nice while you're out, especially? One is the Magic Stick by GroVia, which is all-natural, and the other is California Baby's Non-Burning Diaper Spray.
Both of our parents live out of town, so in traveling to their houses, I'll bring either the diaper pail liner for soiled diapers or a couple large wet bags, and one of the larger wet/dry bags. I will certainly have to have all of my diapers clean before leaving, and bring all of them with me. If we'll be there for more than 2-3 days, then I'll also have to bring stuff for washing the diapers (i.e., detergent).
