Totally agree with you, this has given me ideas. You might consider stating that this is a idea starter rather than an 'idea' in itself. I checked out your parents and teachers edition - great idea, very detailed I left you a positive evaluation. keep up the good work :)
Parents working with their young children on create confidence will show the kids that creative confidence is something to value in there lives due to the parents encouraging the behaviors they will learn doing the actives. Also it will teach parents (in a small way) how to be more childlike.
You could implement this concept into your idea to help build on what the kids could teach parents during the activities. (without taking too much away from your concept)
