I'm due my 3rd baby soon and I've gone down the reusable nappy rote this time, really cant wait to use them, just been thinking about when I'm out & about, DH said just use nappy sacks but feel that they may split while in the changing bag (with all the stuff you have a carry for/with a new born) so I was wondering how/what do you do and/or use? I was thinking about maybe a wash bag/wet bag sort of thing!?
