Firstly: a size 1 applecheeks pocket/cover that I stuffed with a cotton prefold (cut into the size and shape of an insert) and a hemp-cotton Geffen Baby infant doubler. I didn't tighten the waist/legs enough so we did leak a tiny bit of pee out onto the blanket while nursing & napping.
I really liked the fit though! Sadly, that brand is $20 brand new for the cover only. A lady gave it to me as a freebie when o bought some dipes from her off a swap.
