There is freedom in admitting only God is enough. Then we can place our problems, and our children’s problems, in His capable hands. We stop living in reaction to circumstances, rest in His peace and hope in things unseen. As we trust God, seeking His will in our hardest circumstances, He gives new perspective of impossible problems. His eternal perspective.
Whining happens. Especially when children are tired, hungry or bored. One rule has been effective in turning things around.
