Poetry book and new behaviors

Jupiter had a good morning getting ready for school. He had a good day at school. We have noticed at home and they have noticed at school some new behaviors that Jupiter is doing. He is tapping his feet and doing rhythmic things. He does not seem upset by this. I noticed in the mornings before he gets on the bus that he has to tap his feet or he may have to sit up and down on a chair before he will get on the bus. We have to wait a couple of seconds for him to finish and encourage him to come along.
