I had three in cloth for about ten months! They all had seperate piles (had to for size and absorbancy issues). Which also helped anyone else changing them as it was clear whose was whose!
I washed every other day (large washing machine, but really struggled to also have them all in cloth in night, was much easier when the number dropped to two).
I found that I needed a million and ten wipes as they were almost like gold dust if they all had a pooey day!
Going out I would have two nappies per child in the changing bag and then if it was a whole day out there would be a further bag rammed with nappies in the boot of the car to top up with as necessary!
The best bit was admiring the nappies all stacked up neatly, worst bit was keeping up with restuffing them! I also got some satisfaction with gaving them all in cloth, despite the 'oh how much extra work' 'you're mad' comments!
