I have mainly poppered nappies and have no problem tumble drying!
Bambeasy, bamboo baby beehinds and swaddlebee OVs are really slim and both really absorbent! And all come in BTP so an econmic option, WN do lovely cumstomisable wraps, and like rae said ME airflow, but them popolini do a nearly identical wrap called the vento and it's cheaper, these are both fab reliable wraps as are nature babies, Ive found all of these really quite cheap on this site, and the customer service is without a doubt one of the best I've dealt with, http://www.boocoo.co.uk/category_wraps.asp
As for pockets I really think you can't go wrong with them, I love bum genius, and blueberry minky pocket, they are rather pricey but the are also BTP so that works out a bit better, and blueberry have some lovely patterns and fabrics! And you can always add more absorbency if she starts to out wee the inserts that come with, and I'm sure there would be plenty of people here willing to help with stuffing advice!
Night nappies, well I have to say I was also terrified of cloth night nappying but I decided to give it a go, we use night notions from wee notions and huggles (and I have a quickflip as an emergency night nappy) for my nearly 2 year old, and my 5 week old uses bumgenius or blueberry OS for nights! I have to say I have yet to have a leak from a night nappy on Jak and he out wees most of his day nappies if left on for longer than 3 hrs despite huge amounts of boosting, and disposables always leak on him so that wouldnt be an option any way!
As for wanting pretty nappies as your worried about the cost maybe get one or 2 pretty wraps that way you can use them more than a pretty nappy, I love the nature babies orange flowers, or a WN wrap, expensive I guess but you'll get plenty of use out of a wrap! I'm really the wrong person to ask about saving pennies as I have no self control and love the embroideries and pretty minky fabrics, heres a couple of pics of my little girl in her WN wrap and nature babies wrap!
Sorry I just love showing her off, I hope all I've said has helped a little rather than confusing you more!
