REUSABLE NAPPIES-WHAT GOES WHERE?!

megan

So I am around 20 weeks pregnant and I've bought a job lot of reusable nappies from 0-6 months and then 6-12months. There are big rectangle clothes, 3 fold? which I think go inside the 6-12month nappies, and then 2 different types of cloth pads... which I'm not 100% on? Are these the liners that catch the poop or just more stuffings?? Do I need to buy liners? Or are these pads acceptable?? HELP!!
