Infancy is probably the only time when children expect nothing but love from parents. As they grow the expectations grow, like parents like children.
Parents expect quite a lot of things from children from day one. About their appetite, about their smiles, about their sleep, about their various milestones like turning, crawling, walking and then the peak of expectations begin on the day the child starts schooling.
Like parents, like children. They learn to expect from us, parents. We cannot stop expecting and they never stop learning. And this cycle would continue for generations.
There is no specific solution to this by all practical terms. No one can stay without expecting anything. However, we can control what we expect; and that can happen when we know our children well enough. We can also control how we express our expectations to children; and that can happen when we know ourselves well enough.
