Cloth diapers for overnight question

ca

So I decided to start using cloth diapers for overnight because my son was having some leaks in the morning after a 10+ hours of sleep

How can i make cloth diapers more absorbents?

I put two bamboo charcoal inserts and he still have some leaks in the morning

Oh and I purchased one of those bamboo disposables liner but they keep moving should I use more than 2? And how to use them?

He got some big thighs!!
