There's actually a movement where kids don't ever wear diapers. They're potty trained "from birth".I suppose the third option would be to get the timing down and take your kid outside and hold them over the sewer or something. Or take them to a forested area or a farm and do the same thing. Nice and natural that way.
Parents rarely consider what's more environmental friendly. They're concerned more about about cost or practicality, when making their choice.
I think you exaggerate though with the suggestion of making it illegal just because one pollutes more than the other. :lol:
