Much more pleasant for a pooy nappy. In a disposable nappy the liquid gold just pools up, sticks to his bum and sometimes oozes out the sides. ick. It is soaked up by the pre-fold cloth so no oozing or sticking to baby.
Not throwing a ton of stuff away. Major plus in my book!
He usually kicks up a fuss to get changed asap after peeing, so I felt like I was changing him more frequently than in the disposables.
With a little chicken-leg man like Henry, the cover doesn't fit snuggly, so he managed to leak pee out of one leg opening onto my mum (who took it remarkably well!). But he only leaked one out of 12 times.
You have to wash them; though since you always have a ton of baby laundry anyway, this is a minor con, in my opinion.
