i did my 2 boys (although not twins- but 10.5 mths apart) in cloth cause it was clearly cheaper!!, i had a stash of about 35 - washing every 2 days (3 if i was extreamly lucky!)
im now pg again, with suspected twins, have 8 more sleeps till i go see the doc!!! and of course my nappy stash (the ones i made - oh about 30 of them) are stuffed (as int eh PUL is not longer water proof - think i may have brought an inferior product there! so of course i still have 2 in nappies (one tt thank god, and the other is stubborn as all hell) so the stash is being remade, for not only them, but alose the new one! (omg it jsut occured to me - i could have 4 in nappies, 3 if ds1 actaully is tt by the time this pg is over!!!!!
)
plus on top of that, i am currently making preemie sized nappies (for waht was only one baby at first - but now may be 2!) in case i have another early bird! - (got issues with disposables casueing very nasty nappy rashes, in all of the kids so far, and is worse in the little preeime!)
