okay. I cannot figure out what inserts I need..

I have a ton of microfiber, bamboo/MF blend, and some charcoal/bamboo ones. as well as 2 thirsties hemp.

my daughter is 2 and tends to "flood" the diaper - holds it and goes all at once. some of my diapers hold up better than others regardless of the insert.

bum genius 4.0 with MF - no leaks.
alva pocket with mf, OR a cbi, almost instant leaks.

I thought CBI were supposed to be absorbent?

I don't want to have to double up every single diaper - is there such a thing as a hemp doubler to put underneath a mf, cbi or bamboo blend? I LOVE my alva bamboo/mf blends - super trim, even when I have to use two.
