Mmmm, maybe it has to do with the urine? As in some kid's will wreck the bamboo faster than others, ITMS?

I definitely noticed bamboo disintergration, I used to dry pail and wash every second day. I don't think soaking will put me off using cloth, although dry pailing is obviously easier. TBH, all of this does make me think again that although MCN has some great benefits, flats are so much easier!
