I still haven't read the whole thread (not in the mood for arguments) but I agree with Leesha that it's good to read all articles that involve the safety and health of our children. I'd rather have some food for thought than proceed in ignorance. If I discover that I may have made a choice that could have been harmful I guess I hope for the best and move forward. All of us are trying to be the best parents we can be and THAT'S what matters.

Though personally I'm a huge advocate for living in line with nature's design when it comes to our bodies. Convenience and temporary pleasure can be tempting things. When I think of the most harmful things we do to our bodies it's often for these reasons of convenience and short term pleasure. I'm not saying your kids have to be wrapped in cotton wool and bored stiff... like many have said, moderation is the key, as is really thinking about the big picture of what the activity is doing to the body.
