It is remarkable sometimes what you can get out of children when they are away from their parents. They will say you things that will make you smile, and make you cry. In the focus group sessions with kids that I held, it wavered not. I wish I would have taken video of those sessions. However, I found this wonderful blog with some great content and this video, called "The Truth about Sports Parents".
If you are having trouble convincing yourself or someone else about changing behaviours of helicopter parenting, I recommend you watch this short but to the point video, from Richard Cashman, "The Sporting Influencer.".
