I use flushable liners. About $20 for a roll of 250 I think? So what's that, like 10c a nappy change? Did I do that maths right? I'm a bit vague atm...

They don't seem to aggravate my kids' bums. And they mostly catch most of the poop - only if they have been really wriggly or if its a poosplosion does it go off the liner onto the nappy. Overall, very happy with them.
