So I'm getting my first set of prefold cloth diapers. I tried the ones with built in tabs and the velcro breaks down or sticks to unrelated laundry, lol. So yeah, I decided to get a pack of 3 x-small prefolds (skinny me, hehe) and they'll be here in a couple of days... I was wondering though, how long they will last though? Both from how many hours would they last, and how much time before they break down. They're 4-10-4. Any thoughts?
