moderate discipline is okay, discipline your child with love. be able to control your anger when discipline a child, be careful not to vent your anger or frustration about something else on them...they're the product of your love. But western system of child upbringing should never be adopted, we can see the result of such upbringings in western society, foreigners like Indians are the most successful in the western world because they're disciplined...the undisciplined kids ends up being drug addicts, feeling like they're a cat trapped in human body, etc.
THEREFORE, DISCIPLINE MODERATELY WITH LOVE.
