Lis ... that's the system where you just lay a folded up cloth pad of some description down the centre of a cover and fasten it isn't it???
Fortunately ... (or unfortunately depending on your view
) ... all our friends and family are very "old school" ... we've had to teach them how to put on a disposable and most times when we've come to pick him up he's got a terry flat on him!
It's actually astonished us how many people STILL have a few flats lurking around their households ... even after their kiddies have left decades before!
