Overnight diapers?

We just started CD so I haven’t tried a lot yet.. my baby is 10m and sleeps through the night so I need something that won’t leak during the night.

We use Mama Koala and Alva baby pocket diapers!

As of right now we have microfiber inserts, a few cotton. I just ordered 4 layer bamboo charcoal and 5 layer bamboo charcoal.

If I layer the microfiber and bamboo charcoal inserts should that work? Layers will go in the pocket, which order should they go in? Does it matter?
