Hey ladies- My daughter is just over 4 months old & uses Kawaii P&N's. I change her ever 2-3 hours, but recently she is completely soaking through them before the 2 hour mark! I tried using an extra microfiber insert, but it is too bulky. I also tried a prefold, but the leg gussets sit away from my daughters thighs. What can I add, or replace, with the microfiber insert?
