I just spent half an hour doing an online search:
"how to make duck diapers"
I'm losing it, y'all!
The even scarier part is that I found a few people that make and sell duck diapers, so now I realize I'm not the first person to think of it. However...I'm not really willing to purchase these harness/diaper contraptions, because I'm just wanting something temporary for this time when they are little and in the house.
Now that I've seen what they look like, I think we'll do a bit of experimenting....
