I think our job is to raise children who are compassionate and honest and we are required to always be that 'soft place for them to land' when life smashes them down or when they fail at something that they've tried to do or made a mistake. The world can be harsh enough without the one person (or two) who are supposed to protect them and guide them, adding to their misery. And encouragement equally, in my opinion, can be handed out even when they have failed or made a mistake and disappointed. Encouragement to do better, encouragement to see that that is not the best that they can be, encouragement to seek reconciliation for the sake of everyone.
We all do better with encouragement. That pat on the back from an associate, a word of approval or even a bonus from a boss....encouragement in some form.
It's also important to remember that they are children who are inexperienced in the world and our job is to help them understand it, understand their role in it and to understand the dangers of it. Browbeating, hitting, being cold and distant does not teach them to be the best that they can be, in my opinion. It also depends on the children involved. They are not a one size fits all collection of little people and what will suit one child will destroy another.
