Thanks to Myra for this Frugal Baby Tip!
If you wanted to do this really cheaply, then you could get some Gerber DSQs that you'd find at Babies R Us, unfortunately, these are only 4x6x4 (I believe) and not 4x8x4 which might be better suited for a toddler, but then again, some ladies have been having great sales, so you might find some toddler prefolds at a good price.
Then you can get Dappi pull-on pants (I bought some to tide me over, and I'm pretty surprised to find that I like them!). At $3.99 a pair, they are a great price. I wash them by hand, then air-fluff in the dryer and they are ready to go.
Of course, you'd have to use pins to secure your diaper. Or you could buy some Angels which are only I believe $4 a wrap (These are at Born To Love.) which don't require pins.
