Hemp inserts. Two large and four small. If i planned on fully CDing my kids, i must find the best solution towards night time diapering. I read a lot about leaking and so on, and i think trial and error is needed to find the best soaker or insert to be used when they are sleeping. I tried doubling the microfiber inserts, and they failed me miserably! Until my hemp inserts are ready to be used, my DD and DS are both using the sposies at night (when they are sleeping). I hate that..really i do!
