Grubby this is good info thank you! The cheeky wipes info talks about putting the dirty wipes in a box of water so the stains don't set. I was hoping to just rinse off the worst of the poo then chuck them in the nappy bin with the nappies rather than having a separate box, but that means they won't be soaking. (I'm not going to be soaking the nappies, just rinsing off any poo the liners didn't catch then storing them dry in the nappy bin till I wash them) Will that be ok for the cheeky wipes do you reckon? I'm trying to make things as un-faffy as possible 
Also, total over-thinking newbie question coming up... the only space for a changing unit is in the baby's room, though that's only about 6 feet from the bathroom. So I'm thinking we'll change the baby's bum, and get him in a clean nappy, but then how do you manage rinsing off the pooey nappy in the toilet? reasonable when he's newborn and isn't mobile, but once he's getting bigger and wriggly where do I put him so I don't have any poo/baby disasters? I realise this is a ridiculous question, but I have literally no experience of tiny babies and can't quite picture the logistics of how life goes on when you have one!!
