A couple of quick answers:

Money savings - disposables averages about $1000 per year.. so say $2500 from birth to TT (for each child!) and that's allowing for buying in bulk and on special. Cloth - can be as cheap as buying 2 packets of flat nappies for $50! I have spent maybe around $700 on MCN? I haven't actually added it up LOL. But there'll be hardly anything spent on nappies for subsequent kiddies (unless there's some irresistably cute nappies I just HAVE to have!)

Washing - I wash every couple of days. And it's very little effort.. you just chuck the nappy in a dry bucket.. then in a couple of days, empty the bucket into the machine and wash! easy! So it's not like you're spending a lot of time in the laundry or anything
