Depending on how heavy wetting your LO is, you might be best with fitteds rather than pockets. I prefer fitteds because they seem less bulky as the nappy itself is absorbent. DD is quite a light wetter overnight. We use Bumhuggers (quite cheap, particularly if you can get them second hand. And the newer style have a pull out soaker for quicker drying, where you can also stuff additional hemp if you need extra absorbency.), Bedbugs (lots more expensive and not great if you have a heavy wetter, because of the MF in them) and FF Nights (nigh on impossible to get hold of
). We used to use Baby Beehinds, but Iris has become such a super soaker during the day that they've been relegated to day nappies as I don't have enough fitteds and we can't us pockets ATM.
But they always worked well for us and being bamboo they holds loads. Wool over fitteds is a great combo, as it's breathable and allows evaporation, so night nappies seem less damp come morning.
