I am part of the group of people that is totally against aggression in children and adolescents, since it is proven that the child until his 7 years is still in development stage, not having totally the sense of what is right and wrong. In addition, even if you are the parent, anyone has the right not to be assaulted, this becomes an abuse, and depending on the severity and amount of aggression the child receives, it becomes a traumatic problem for the child.
My mother has always been braver than my father, so she has assaulted me a few times, while my father always solved everything by talking. Using my father as an example, he proved that I do not need to be assaulted to behave as a child or as a person. Most of the friends I have who have been assaulted several times as a way to receive education, have become violent people in the future, using aggression to solve anything, which for me is worrying.
Anywhere you will hear that the basis for solving everything will be dialogue, whether at school or even at your job, so why bullying a child? If you've been assaulted and you think nothing has shaken you about it, that's fine, but each case is a case. Besides, nobody likes to be beaten, and probably you did not like it too, so we all managed to do differently with our future children, cousins, friends and show that it is not the violence that will solve, because in fact you will only create a field of battle between you and your son, and probably when he is older, will face you and try to defend yourself.
