Ranvir has a four-year-old son - Haroon, with actress Konkona Sen Sharma. The couple recently announced their separation.
"I am no expert on parenting. My son is four-year-old, so I am fresh father. Since, I have become a parent.. I feel if you sit down and get through your child and use one's understanding to teach them something.. Is the easiest way," Ranvir told PTI.
The 43-year-old actor, who enjoys a fair share of both critically-acclaimed and hit commercial films, says corporal punishment is most "flawed" form of teaching to children.
Even as a child, Ranvir said, he used get thrashed by his brothers.
"I had two elder brothers and they would thrash me if I do something wrong, then dad would thrash me. I think corporal punishment as disciplining the child is what I am questioning.. I feel there are less flawed methods."
The "Mithya" actor will be next seen in crime drama "Titli" set in a Delhi slum, and is about a family engaged in car-jacking. The film will release this Friday.
