I'm experimenting with different nighttime solutions. I have these thirsties duo inserts where it is 2 layers snapped together - one MF, and one hemp/cotton blend. I tried 2 of them together (so 4 layers) plus a bamboo insert I have, but it was so bulky. Could I maybe just use the hemp/cotton layers and ditch the MF altogether, or will he pee "too fast" and the cotton won't soak it up as readily? I feel like I've read that materials like hemp and such should always be paired with MF bc they absorb more slowly than MF?
