A few people asked for more current info on dumping fecal matter out of disposable diapers in an earlier post (which I know most people don't do)- here it is, straight off of Pamper's own website:
"Waste removal
As the Pampers bag recommends, you'll want to dump bowel movements in the toilet. Then just roll the diaper into its backsheet, using the tape or fasteners to keep it closed, and dispose of it in the trash."
Not trashing anyone's choice to use disposables.
