As if raising kids isn't difficult enough without having to worry so much just about the nappies you choose
If raising kids made simple, ethical decisions too inconvenient to consider, I wouldn't want to have kids. Having children shouldn't compromise what you believe in just because it might be challenging, or you might be tired. I imagine my experience of being a mother will be something that makes me want to strive to be a better person - more than anything else I've ever done will. At least, that's what many people with children have told me, and it rings true. If I let myself down on something like this, I wouldn't be being a better person. I wouldn't be being true to myself and the things I feel to be right - and I would be undermining my efforts to teach my child to do what is right, instead of what is easy. Sure, some people might think it's just nappies - but big things start with small decisions, and for me the environmental impact is an issue that is not to be ignored for my convenience.
I have never understood why, when presented with a viable, and more ethically sound alternative, people still choose against it. But again, that's just the way I am. And I have to say, I hope I will successfully raise my child to be that way as well. But they are born with their own personalities. All you can do is try to guide them to decisions that will work out best for them, and teach them to be thoughtful, considerate and socially conscious.
