I work in a mat unit and they dont have anything set up for mums to use, the nappies we have are disposables that people have given us (ones mums havent used as their babys grew out of them), the management are crap as it is so there would be no chance this would be added to their list of things to do (it took months and months to get a new fridge after the last broke), i think its possible without the hospitals help if the mum takes a wet bag and someone takes it home every night, but it would prob mean extra bags and some units wouldnt be too pleased with that
plus there's no 'need' for it as almost everyone round here have no idea about cloth nappies and there brilliance
and that goes for staff too
often staff change nappies and i know that if it was anymore difficult than nappy off, wipe, nappy on, go, then it just wouldn't work due to sudden changes of situation i.e. one minute quiet, the next; 3 labourers, a million phone calls etc, depending on the type of cloth nappy it can take longer if you havent used them before, but i think more encouragement should be given to mums to use cloth from the beginning, nurseries too!
but i do still think they should have a bit of formula in the hospital, there are situations where this is needed, and im really really pro breastfeeding, but sometimes its not possible for someone to go get milk at 3am for a baby that needs it and sometimes it is needed sadly
