When my mother gave birth to my younger brother, she started using cloth diapers on him, worried about the environmental impact of disposable diapers like the ones she used on me during my childhood. She went back to disposable in less than a month.
I used cloth diapers for both or my children and do lots of other inconvenient things for environmental reasons, so that I can feel good about my own behavior and choices. Many other people are the same.
