We haven't had to deal with solid poop yet.... but yeah, when that time comes, dump in toilet, and throw in pail....then do a cold soak cycle and then wash on hot, with a double rinse cold. The machine does ALL the work. You just have to use one of the recomended detergents with whichever diaper you choose.
I am used to dumping poop in the toilet anyways as I am getting Hunter ready to train - and one of the first things I do is show how poop goes in and flush

Not sure if that works, but with ds#1 it seemed "fun" and then bam he was trained...
It would be so nice to just have 1 in diapers again
