A little conversation on the subject of the inquiry, giving the child an opportunity _to hear and to use language_ in respect to it, is often all that is required.
It must be remembered that the power to express thoughts, or to represent external objects by language, is a new power to young children, and, like all other new powers, the mere exercise of it gives great pleasure.

If a person in full health and vigor were suddenly to acquire the art of flying, he would take great pleasure in moving, by means of his wings, through the air from one high point to another, not because he had any object in visiting those high points, but because it would give him pleasure to find that he could do so, and to exercise his newly acquired power.

So with children in their talk.

They talk often, perhaps generally, for the sake of the _pleasure of talking_, not for the sake of what they have to say.

So, if you will only talk with them and allow them to talk to you about any thing that interests them, they are pleased, whether you communicate to them any new information or not.
