While you're at it, why don't you tell them about our thinning ozone layer and how one day we won't be able to breathe, I'm sure that'll make for a great bedtime story. Don't get me wrong, I think it's a good conversation to have with our children, mostly the importance of recycling and reusing.....but I've never heard of a child going to bed with visions of composting dancing through his or her head....lol
Any kid attending school most likely knows about that stuff anyhow.
But I'm not talking about mundane things like composting, I'm talking more about the wonder of the universe, and all of it's magnificent glory. It used to mesmerise me as a child to hear... and when one of my teachers at school taught us about our solar system, the entire class was mesmerised.
