How much do I demand from my children?

One of the questions that floats in my mind is how much do I demand from my daughter, do I want her to be emaciated? Maybe I want her to achieve things that I could not at her age, is this valid, or am I making a mistake by doing this, these are valid concerns that as parents we have to face, measure the demands to our children, keep in mind that childhood is the best stage of them, of all human beings.
Every stage of our lives has its complications and demands, and as parents perhaps we are shortening this beautiful stage of relaxation, the desire that they perform at school is a pressure that falls on their shoulders and we have to measure that burden, our duty is to relieve the burden, not make it heavier, we believe that we live in a constant competition where children have to stand out over other children.
The psychological pressure is strong towards them, there will be children who adapt quickly because they have no other choice, and what happens to those children who cannot do it, they are trapped in their helplessness of not being able to do anything because it is the parents who induce them to collapse, is it possible not to realize the risk of shortening their childhood?
If we care about their future, we have to let them express their concerns so that we are not part of their burden, at some point they will have to understand the degree of responsibility they have to assume, they will do it as they grow and adapt to the beginning of their school years.
Let's try as much as possible to be parents that we do not extralimite us with the demands to our children, if we do these we are taking them to a lifestyle with stress, by the overload that we place on their shoulders, remember that they have their school responsibilities and if saturated with extracurricular activities can reach the collapse and that no parent wants it, I try to take in family the daily activities of my daughter to feel our parental support.
