It can be really frustrating cant it?
First of all, i would ditch the pockets, but then i havnt had any luck with pockets...we always get leaks no matter what we stuff with, i just dont find them any where near as reliable as fitteds. Secondly, have you tried a bamboo fitted? Bamboo little lambs are FAB and really cheap if you find them on classifieds? As for the clothes issue, we use wool full time so dont have that issue but what about leggings/joggers/dungeree's? (sorry cant remember off the top of my head if your LO is a girl or boy!).
I guess it all comes down to how much you want cloth to work...if your happier using nature babies disposables then use them (although i do recall someone posting that nature babies still contained nasty chemicals and that they dont biodegrade unless you compost them yourself) so it would depend on your reasons for wanting to use cloth..

Hope you work it all out!
