Sazz, you change the shell of the pocket nappy every time too, the thing people like about pocket nappies is that you can adjust the absorbency to suit how your baby wets, and because the stuffing comes out, they dry quicker! I used BumGenius One size pockets on River from birth, they were the only ones that didn't leak his nb poos out, they were our shopping nappy! They can be hard to come by these days, think you can pre-order them from some places, like Nurture Nappies.

Good idea about the bbh, you can always buy more if you decide you really like them. I didn't start to love my BBH til Riv was a little older though, just liked them at the start.
