Well, I am pleased to say that after a couple of days using prefolds / pockets / AIO, I finally put Laura in one overnight (yep - 12 hours!) And there were no leaks this morning when I got her up!!
I did make sure she was well-padded tho! Two inserts plus a hemp insert
Need to get some more MCNs to go full-time tho - especially trying to dry anything in Auckland's winter
