I didn't feel any movement with DS until I was about 20 weeks - I think it's really difficult to be absolutely positive with a first baby for one, as you're not sure what you're 'looking' for. Also the placenta was anterior (at the front) with me so that 'muffled' movement quite a bit.
Re-usable nappies are great!! Honestly! Still using them with DS and we don't have a tumble dryer (would kind of negate the environmental benefits in my opinion). Yes they are an expensive outlay in one go but I think then overall they work out cheaper in the long run, especially if you plan to use them with more than one baby.
We used a combination of bamboo nappies and Fluffles - bamboo absorb more but take longer to dry, fluffles dry sooo quickly.
Only downside is that you have to buy bigger trousers / 'cut for cloth' style trousers to accommodate the extra bulk. We got some cut4cloth clothes on eBay quite reasonably, or clothes in stretchy fabric are ok as well - jeans can be a bit of a problem! dungarees great as well.
I would advise using disposables overnight though, last thing you need when you get up for a 3am feed is to discover the baby is wet through and you need to not only change him, but sleepsuit and all bedding as well!
Again Ebay great for price comparisons on nappies.
