So what... About two years ago I did some experiments: How long can resist and how to do more bulky diaper. Ended with five, but when it was completely full, it started going down, beacuse heavy. I did three - four line cuts in the diapers for inside use and put another without those holes over. In practic way I can do it maximum with (for example) with two tena green or three blue. Did you tryed something similar ?
