Yoga is something I would like to be much better at. I love the stretching and exercise component but I am hopeless at the 'switching off' component. Schools are beginning to incorporate many of the good aspects of yoga into daily practice though, and I am asked by teachers and parents what book resources are in the library on yoga. Here is my pinterest page listing many of the books I have managed to collect. The teachers seem to like ones where the movements equate with animal shapes, like You Are a Lion by Taeeun Yoo and I Am Yoga by Susan Verde and Peter Reynolds is a particularly good introduction for any teacher or child wanting to learn what yoga is all about.
