The Canadian Association of Principals (http://cdnprincipals.org/) endorses the CBC Documentary, “Angry Kids & Stressed Out Parents.” From their website: “The documentary follows children and parents enrolled in groundbreaking early childhood interventions that are currently being used or piloted in various parts of Canada — at home, in school and in the community — to help children (especially those at-risk because of Adverse Childhood Experiences) master the skills they need to be successful later in life.” You can watch the trailer here: https://www.youtube.com/watch?v=I-BZNSAyNk8&feature=youtu.be and the whole series of videos at the headline link, above.
