I use a pocket diaper stuffed with a shaped insert (like a wonderfulls
but I only use 1 large one), and a bummis stay dry doubler on TOP of the diaper.
I find the shaped insert to hold more pee, because the mf fills the whole front. I found that sometimes the fleece wouldn't absorb fast enough and some pee would leak, so that's the reason for the bummis doubler on top- it's stay dry, but it's mesh instead of fleece, so it can't (I imagine) repel. That absorbs fast, then wicks it through the fleece to the microfiber.
