I'm definitely going down the re-usables route - better for the environment etc. etc... not necessarily better for my sanity, nor our septic tank, but I am pretty determined. Our local council offers a voucher scheme to help you get started on real nappies. This week, until Sunday, is Real Nappy Week and there are lots of offers around.
I've only just started to buy mine and it is REALLY confusing, but I'm going to go with just a few to start with, in different makes, to see what works for me. We will supplement with eco disposables for a while, especially if baby is small at first because some cloth nappies don't fit newborns that well.
I can't explain everything I've learned... just take your time reading and looking and you'll work it out soon. I think a good way to start is to just start with a few and try them for daytime or something to see if they suit you. If they don't, there are lots of people willing to buy them second hand from you, so you won't lose too much money for having given them a go.
