Here's what I've got on heavy rotation on my iPod:
After jamming, I can *calmly* remind those in-the-know, and reassure those inexperienced with early childhood/kindergarten aged students:
Perfection doesn't happen the first week of school.
Perfection certainly doesn't happen the second day of school.
Accidents, unexpected noises, apprehension, and joyful exuberance are NORMAL, though their timing might not always be convenient.
Accept it. Breathe.
You gotta be cool, you gotta be calm
You gotta stay together
All I know, all I know, love will save the day
