LOL Liz, you will just have to start making them, and sell them instead!

Hey Ryn This is all very fresh to me, Riv's been in cloth 5 weeks now! Well actually less than that..

1. I can only speak from my experience, but Riv wets every nappy, it's the constant pooing that's settled down now. He used to poo in every nappy, now he saves it up (it's delightful). I found sposies to be sooo handy though, for when he was squealing or kicking and I couldn't find a cover or when he wee'd on the nappy before I'd even fastened it...for those times, it was sanity saving just to reach for a sposie
Then you can eeease yourself into cloth and it's much more fun that way I reckon.

2. With newborn fitteds, you just don't know how big Liebling will be...if I'd got nb size fitteds, Riv was 4.2 kg (9.4lb) so he wouldn't have been in those long, if ever! He didn't fit a lot of 0000 stuff. For easy pockets, the BumGenius seems to fit babies well, and contain poo well. His Happy Heiny fits well too. They're both USA brands I think.
I am awful with pins too, and awful at the flannel origami! But I LOVE my prefolds and snappis. They didn't take me long to get the hang of, and they are small, can be used as spew rags too, can be boosted for big wee'ers, and dry pretty quickly. So perhaps consider getting some prefolds, since they can always be used for other things if you don't like them that much?

3. I have 12 prefolds and 24 flannels. (DH uses the flannels) and about 8 fitteds that I use. Just do some maths I guess, about 10 nappies a day, and how often you'll wash.
Then allow for nappies you'll use as spew/poo/misc rags, and for when bubs wee's as you're putting the nappy on and for when you miss a washing day.
In other words. Get as many as you need, and then some.

4. I try for every 2 days, sometimes more often and sometimes less often. The bucket takes about 1-2 days to fill. Prefolds and flannels dry pretty quickly, pockets do too (but their inserts take longer), AIO's and fitteds can take a fair while.

5. Features I like.
- One size are economical. BBH's are bulky, but absorbent. BumG's are pretty darned trim if you buy a small insert for them, the one they come with needs to be folded for the small setting, which really isn't that bad, I'm just fussy.
Sized obviously fit more specifically though. If that makes sense.
- Velcro is good for a wiggly baby I reckon. Mine's wiggly. But then snaps don't get caught on things in the wash if you forget to use the fold over tabs for washing.

The only other things I can think of that I'm learning is, just buy one or two of your modern nappies (unless you're happy to re-sell them for a bit cheaper if they don't work out) until you're sure you like them and they work for you. Eg, some nappies are better for chunky legged kids, or babies with a skinny waist, or super wee'ers.

I could go on, but I've probably waffled on enough, hope there's been something in that that's been helpful!
