Oops, I mean disposable vs cloth. There have been several(?) studies (e.g. Union of Concerned Scientists) showing it is basically a wash between the two choices. Cloth causes more water pollution and disposable more land/air pollution. Seventh Generation are the best, most eco for daytime use (amazon.com) and use “normal” ones at night since they absorb more so mom can sleep better. But the scent! Ugh!
