Just thought I'd add a little to the conversation on reusable nappies. We used cloth for DS (he's potty trained now, the joy!), it IS more work that disposables but not outrageous. I'm tempted to give it a miss since we're having twins but DH pointed out that the cost savings mean we really should do it, twins is going to be tough for us financially and we already have the nappies so they will be "free" (only cost is washing).
We used Mio Solo reusable's, they are an all-in-one type which means no separate bits. They have an absorbent liner that tucks into a pocket but the liner is still attached to the main nappy, rather than separate. I would recommend them however what I would REALLY recommend is seeing if anyone near you does a "Nappy-lending kit". We did this, basically borrowed a large set of nappies (and reusable wipes) for a couple of weeks and tried them all to see what suited us (and suited DS, some nappies suit different shaped babies) - ours was via the NCT. We had 16 nappies, it was plenty and meant that in the early months we washed every 2 days. We almost always air-dried - drying outside helps keep the nappies looking and smelling fresher, its cheaper and better for the environment. We used a disposable at night, we tried various night-time cloth nappies (from the lending kit) and found them too much faff/not effective - but everyone is different :)
Finally: we used a liner to catch poo, it made is easier to just tip the poo into the toilet and protected the nappy. We used disposable liners but you can get cloth ones. We had a bag that we kept in the change bag that could hold 2 or at a push 3 dirty nappies so we could go out for the day.
Sorry such a long post :)
