existence of reality in the world.

let him or her growup and experience them by themselves

I think in this era, we should tell the truth of live, so they can ready to grow in this though world. I think let the child grow up with their own experiences is good as far as we also control from far as their parents.

I'd rather let my child learn it on her own as she grow. If I bombard her with information about the harsh realities and problems of this world at a young age, she might be disillusioned and grow up to be a pessimistic person. What I think I can do is to instill good values on her at a young age, guide her to the right path, so that someday she will make good decisions in life. Good values is the best foundation that we could give our kids. They will be able to survive this harsh world as long as they are founded on good values.
