Teaching Buddhist concepts to a child

The post here specifically refers to introducing Buddhism to a child as well as meditation and recitals.

Being surrounded by children under the age of 4, I observe that certain behaviors are starting to take root e.g. clinging. If a particular toy is lost or not available, the child senses a deep loss which results in emotional and physical distress. The kids also identify with themselves with the things they are surrounded by e.g. friends, physical objects, etc
