Stop right there! Don't go buying a complete system before bubs arrives! I haven't used ecobots personally - for all I know they're great - but I just wanted to say please, please trial a few different types of nappy before you shell out that sort of money. (I spent a few hundred on one type of nappy while I was still pregnant, before I'd really seen the wealth of options in MCNs, and really regretted it!)
Prefolds and covers are among the cheapest of cloth nappy systems, and are apparently good for newborns, but IMO there are much better options out there.
If you're worried about cost you can make pocket nappies really cheaply
I'd really recommend getting a hire kit or buying a couple of a few different types of nappy before you make a decision one way or another.
Real Nappy Week is only a month away, might pay to check out the Expo in Western Springs on May 2nd (actually I will post a separate thread about this). There will be a bunch of different brands/types of nappy there and also some people doing some sewing demonstrations so you can see how easy it is.
