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

The question i am seeking to answer though is the introduction of concepts such as clinging, letting go, intent, self, no-self and the like. 

Being surrounded by children under the age of 4, i can 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
Try the videos under the section of Children on this website.

There are some ebooks for children here.

There's a simplified introduction to Buddhism for kids here.

There are websites on Jataka Tales for children here, here and here.

I think a great way of teaching Buddhist concepts to children is through stories. Stories are entertaining to young children who need their creativity and imagination stimulated, in order to learn things happily and efficiently.

Instead of trying to teach very young children concepts like anatta which may be too difficult for them, it might be better to teach them virtues and good moral values, which are available through the Jataka Tales and some Dhammapada stories. This is the foundation to inculcating sila.
