I love this idea and wish we could try it here. The article describes different ways of calming children throughout the day and helping them find ways to calm themselves. (I remember this from baby books about trying to help babies learn to comfort themselves if they woke up in the night and thus being about to fall asleep on their own.)
I believe we live in a busy, go, go world that gets easily impressed on our children, from teachers trying to cover test material to parents trying to fit everything in. We have a noisy life with beeps, buzzes, sounds coming from every direction. Five minutes out of the day to calm the mind might be a good thing.
