Regards appreciated @rokhani.
Interesting and valuable advice.

But we must also get into the minds of certain parents and other external factors. What do I mean?

.- Enter into the minds of parents. There is an instinct or feeling to please our children due to a lack lived in our childhood. The father who always wanted a toy and never had it. When he has his own children then he wants to give them.

.- External factors. The economic situation in many nations of the world pressures parents to say no. But they must do it with great pain in their hearts. Denying a request to a child can be very painful when he asks for food and you do not have the resources to provide it.

Thanks for sharing these tips. Excuse me if my vision of things is too realistic.

All best, Piotr.
