What else will I need?
Diapers - enough to last 2-3 days.
Wipes - You can make your own wipe solution too or just use warm water. Baby wash cloths make great wipes, and they are cheap too.
A diaper pail - Optional, you can keep them in a hanging pail liner. You can buy a trash bin from the store. Whatever looks good to you should work :) It's nice to have a lid. Popular choices are bullet style and roll top style. Some kinds with a pedal to pop the lid open work well too, though depending on how it's constucted, a pail liner may not be able to fit around the top.
Pail liner - Optional, but really nice to not have to scrub out the pail every day. You can wash the pail liner just like you would wash a diaper cover.
Detergent - something diaper safe!
Tea Tree Oil, Sportswash, Calgon Water Softener, Vinegar, Baking soda - all of these are optional, but may help get the diapers just a little bit cleaner. Wash them a few times first and see how it goes.
Wet bag - Optional, Nice to have when you're out and need to change a diaper. You can also use plastic bags.
Pins or Snappis - Optional, nice if you want to use prefolds, but you can always just lay a prefold in a cover.
Rash Cream - Make sure it's safe for cloth diapers!
