Thirsties hemp inserts. Super absorbent. I stuff my BG pockets with one of these and the mf doubler (only to make myself feel better that I'm using two inserts, I don't think the doublers hold much) and my heavy wetter DD has gone over 5 hours in one with no leaks. You know, like when you're out and about and somebody falls asleep in the car on the way home, then proceeds to have a two hour nap? All in the same diaper? I was nervous at first and was sure I was going to be washing clothes and bed sheets but everything except the inserts were dry.
