WNNN on Ryan (though I need to get one of mine back that I lent as I'm struggling to keep them washed/dried!) and wool on top (sometimes fleece but he's nearly out of his XL flongies!
)
Lucas has only been back in wool at night for a few weeks, and we're using a mix of: DNF, LL bamboo, Motherease Sandys bamboo, lollipop bamboo- all usually boosted with extra bamboo/hemp/zorb depending on what is dry and to hand when I'm putting nappies together. Also wool on top.
