Cookie Monster is famous for devouring cookies as soon as he sees them. He has not been much of a role model for self control. The folks at Sesame Street must have recognized the opportunity that the Cookie Monster has to change this lesson. In this video he sings about self-regulation and taking a deep breath as a part of a larger executive functioning curriculum push from Sesame Street this season.
On their Youtube channel they wrote:
"'Sesame Street' launches its 44th season on September 16th, 2013 with a new self-regulation and executive function curriculum. Cookie Monster, the poster-child for someone needing to master self-regulation skills, attempts to explain these concepts while devising personal strategies on waiting to eat a cookie."
