tjhbahr I don't think that they hold up quite as well. All but one of my bamboo diapers that I purchased new are no longer functional - they don't hold enough pee. The one that I am still using is a replacement for one that got bald spots from the first batch before ME changed the fabric. I still have several cotton Sandys that I purchased in used condition that are in useable condition. In my opinion if you are planning on having multiple children I would choose cotton.
