If we notice a sad child

It usually spends that often the children turn out to be sad and when we ask them they say to us that nothing happens: What is what happens to them?

To answer this question it is worth while clarifying that it is not common that our children tell us absolutely everything. His intimacy must be respected so as the biggest it can have problems that it needs to solve them only.
But if we must demonstrate to him that he can trust in us and that we will give him support and consolation.
We must not judge it but understand it and overwhelm it. By no means it is necessary to submit it to police examinations.
If the time happens and the parents notice that the attitude continues, the consultation with a professional can be suitable.
