I've been using MCN for almost a year and I have found that flushable liners just annoy me. DD2's poops just go everywhere and miss the liner most of the time. Occasionally I use microfleece liners if I am using a cream on her bot and if the nappy rash is bad I use raw silk liners. Other than that I don't use anything and put the nappies in the sun to get rid of any stains that might appear.

Other MCN users have a 'little squirt' which attaches to the toilet to squirt away the mess but I've never got one. DH and I just scrape or roll the solids into the toilet and the rince the nappy prior to putting it into the washing machine. if it is really messy then I do a double rince before the wash cycle in the machine.

Good luck with the MCN!
