I haven't even asked to be honest. If we are in charge of nappy changes I don't see that they can complain, its not like we'll be expecting them to wash them or anything! Our local trust has a new recycling policy (about time, shocking the way we use resources in hospitals). I think if you gently point out it costs them money to incinerate your despicables but doesn't cost them a penny to let you take your cloth home to wash, they would have to concede its better to cloth bum a full term healthy baby. I don't want to have this argument though so will just turn up with our stash and see. Its in my birth plan and no-one has been bothered, but then no-one seems to read those things anyway!
Thinking ahead for us, if they have to be in SCBU for any reason I accept that we might not be in charge of all nappy changes or that there might be good reasons to be nappy free or despicabled up ie minimal distubance.
He he, lets see how it all works out, I've been so set on cloth asap for so long, things are bound to get complicated
