While I do know that a positive education is the best way to go, it is not always easy to do it. For sure it is hard after a hard day at work or when we are tired of ourselves.
We rarely punish them but if they do cross the border, a punishment will take into effect.
Most of the times, it is not playing on the Playstation or Ipad (not that they are allowed to do that often, only a few hours per week). But the punishment also has as a result that we do play more board games with them!

Cheers,
