Maybe they protected against this ... but it seems to me that if you have a child who happens to be temperamental, you may start with passive techniques: read or sing the child to sleep. But they are temperamental. It doesn’t work. So, you need to try some else: take a walk, take them for a drive. Maybe that is more successful.
So, do active techniques create temperamental children, or do temperamental children require active techniques?
Is adding wiskey to a childs bottle an active or passive technic? Asking for a friend.
