When I had VanGoghKid (that's the online alias I use for my child), I was 18 and a single mother with few independent resources. My mom showed me how to use cloth diapers and that's what my child wore whenever we were at home. I saved a ton of money that way.
I kept a little bucket in the room, containing water and a touch of bleach. I flushed the wipes and major #2 deposits into the toilet. Dirty diapers went into the bucket and then when it was full, I deposited it straight into the washing machine.
A bottle of bleach could be purchased for less than a dollar. I used an empty detergent bucket to hold the diapers (the top made it perfect, because it could be sealed shut). I purchased about 6 or 7 dozen cloth diapers and some safety pins. That was basically all of the supplies I needed. For less than I would have spent for a month of plastic disposable diapers, I had everything I needed for close to a year of usage. I could have saved more money by using wash clothes for wipes and thrown them in the bucket too, but I did use the disposable flushable version instead.
It was a great investment for so many reasons. My child has very sensitive skin, so all but one brand of plastic diapers gave her an allergic reaction. It was just my luck that this one brand was Pampers Premium and it was one of the most expensive brands in the store. However, a big package of plastic diapers would last an entire month, because they were only used when we were out and about.
Cloth diapers never gave her any problems, because we used a mild detergent for people with sensitive skin. Plus, cloth diapers are extremely versatile. They can be used a diaper, a bib, a wash cloth, insulation for cold or hot foods, and so much more!
