Does anybody know where the cheapest place to buy pop-ins is? Also, is the dream dri one as absorbant as the normal bamboo one? We don't have a tumble dryer so I'd prefer microfibre but if bamboo is more absorbant, I'll just buy a few more if they take ages to dry. I'm trying to get Leyla in cloth overnight but I don't trust any of the nappies we have so far!
