Ummm no! I had 12 for DD1 and I washed every day. I always had enough and the washing was easy to keep up with. I would think that if you wash every second day then you wouldn't need more than 20. I probably used 7-8 a day so there was always a rotation of some ready to go, some in the wash and some drying. With cloth you probably wouldn't want to leave the washing for more than every second day as things start to smell! I had 12 smalls and 12 large for my DD1 and that was all I ever used in total - I then used these for DD2.

With MCNs you dry pail them after you change them. If they are pooey then you use a scraper or Little Squirt to get rid of the poo in the loo before you bucket them. I would wash daily but I washed daily anyway with chucky babies as they went through so many clothes. DP would generally put the nappies on to wash overnight and hang them out first thing in the morning for maximum drying time.

At night, initially DP would change bub halfway through the feed as they do tend to fall asleep on the boob so to way them up for the other side a nappy change does the trick. We had a change mat set up with nappies at the end of the bed so DP would change the baby, give her back to me and then go and clean up the nappy. As they get older they often don't need the change so unless there was a poo I wouldn't do it.
