Phew! Some replies, I was beginning to think all the family-clothers had gone!!!
Well I had a chat to the kids and they were keen to try so I cut up some flannelette sheets as still haven't been out to get some toilet roll as feeling lousy. Kids helped me distribute in each (3) bathroom. Then they promptly ALL went tothe toilet!!

Everyone seems to like it, really soft in comparison and DD3 (3) keeps shouting from the bathroom, I didn't flush the wipe Mummy! So you never know she might remember!
Spoke to DH about it at lunchbreak and he thought it was a great idea. He has always hated how much toilet roll us girls get through

So yes, I'm hoping with the 5-2 gender ratio, it should make a difference. And I finally found the really old thread about this and read the best way (TMI warning!!!) for no.2s is one wipe with loo roll first then cloth. We will see how we go and I may convert in the future. Not yet though!
Now to go and make a wetbag for each bathroom....
