I'm using small Itti Bitti SIOs during the day on DD but we need to change/check on them every two hours or so as she's quite a heavy wetter. I don't want to buy extra Itti Bitti boosters for them as she's currently in the small size and I expect she'll need to move up to mediums soon (got a preloved medium on its way for sizing!). She's 10wks and 13+lbs. For her comfort and my convenience I'm currently using disposables at night because she can sleep 4-5hrs. Previously she's soaked herself and the crib (this was at 5-6wks old when I first started using them) - they were done up tight and we tried a few popper combinations. I suspect gravity was playing a part as leaked back and back of legs.
However, we really want to be 100% reuseable but don't know where to start. What I need to know from all you experienced MNers is... what is a good absorbent nappy that won't leak when she's lying down over night?
Please also let me know all the extras I'll need too (as don't quite get which ones need liners and wraps - hence getting Itti Bittis!).
All your help is greatly appreciated, thanks.
