No matter how much we scream or hit our kids for their misbehaviour, back talks, hitting, throwing things, biting; it is not going to stop.
Because we're trying to solve these issues in a wrong manner.
The need is to first address the reason of misbehaviour.
Yelling and hitting is just suppressing their misbehaviour at that moment, which will re-arise.
Because the underlying need is still unmet.
Remain in close proximity of your kids whilst their aggression, let them vent out and then cool down.
Now is your time to take control of the situation. Offer love. And then talk. Know the reason. And help them solve with your wisdom, so that the intensity of this aggression is lessened the next time it emanates.
