The research and literature related to raising children with high Emotional Intelligence is exploding. I have been following a blog called Half Full: Science for Raising Happy Kids. The author of this blog is Christine Carter, Ph.D. and she is a sociologist and the executive director of UC Berkeley's Greater Good Science Center. She blogs about the research behind rearing happy children. Here she is on YouTube discussing parenting tips for encouraging gratitude in children.
The research clearly indicates that gratitude promotes happiness in adults. Sharing this habit with the children in our lives gives them a leg up socially and emotionally.
