If you want to parent differently and more effectively than past generations then it's time to dump the "old school" way of controlling children's behavior. But don't just "do the opposite" because that can create problems too! Yes, you can get short-term results with extreme approaches, but you pay the price later. Plus, long-term research shows, consistently, that these approaches get negative long-term results.
Instead, use a Balanced parenting style to teach children how to behave, help them develop skills and qualities that make them want to be good people, and hold them accountable for their mistakes in ways that teach children to be self-disciplined.
Dump those outdated tactics that just don't work anymore, like threats, timeouts, grounding, restrictions, and corporal punishment. Replace them with the 5 most effective discipline tools that address the root cause of problematic behavior. When the cause is resolved, problematic behavior often disappears.
