Quoting ricca n baby:" My sister cloth diapered for her children and sent me 12 really nice all in one cloth diapers. The babysitter ... [snip!] ... of money to spend on disposable diapers so I was wondering how well the no name brand (target or walmart) of diapers hold up?"
If you are using AIO diapers, they should be super simple for a babysitter to use, just put em on and take em off. Instead of throwing them out, toss them in a pail. Scrape them when you get home.
But, the Parents Choice diapers sucked for us. Our kids all leaked out of them. No help on the Target brand, but I've heard good things about them.
ETA: 12 diapers might be tough, even with washing everyday. Little ones go through them like crazy at the first! I'd recommend looking into covers with prefolds, cheap and easy!
