Philosophy....Is it helpful for children? How can we introduce it to them?

I have been wondering.....is Philosophy helpful for children? Are they able to understand simple concepts in Philosophy? Will the concepts help to motivate them and stimulate their thinking? Will it make learning and school more interesting for the pupils?

There is a possibility and I believe in that. Pupils are still at their infancy stage of understanding what goes on around them and what the world is about. If we are able to stimulate them using philosophical ideas, we get them to think deeper about life. They get to explore principles and concepts and ultimately, there could be significant impact on how they make decisions and live their lives?

Then the question is whether philosophy and religions have conflicts. There may be. How do we draw the line? Where do we draw the line? I wonder....
