"The only evolution that has happened in me is that I have become more responsible. Responsibility comes when children come into your life," Karanvir told IANS over phone from Mumbai.
Karan married model-VJ Teejay Sidhu in 2006. The two became parents to two twin girls -- Vienna Bohra and Raya Bella Bohra -- in October 2016.
The 34-year-old actor feels men now prefer to spend more time with their children.
"The evolution I have seen from my father's time is that my father used to tell me, and even tells me right now, that he never put his babies to bed. My doctor also said that they were never around babies, but now the evolution is that the fathers have got involved a lot into their baby's life. So, it's easy for the mother also," he added.
The actor says it's a good evolution that has happened.
He says having his mother, mother-in-law and sister around has been a great help in handling the 9-month-old twins.
But Karanvir, who is popularly remembered as Viraj Dobriyal from the thriller show "Dil Se Di Dua... Saubhagyavati Bhava?", describes parenthood as a "different experience".
"So we are responsible and caring, but we are really blessed that these little angles are in our lives. Sometimes me and Teejay wonder what karma we have done that they've been sent to us. They are really God's blessings," he added.
How is he managing his work and personal life being a celebrity?
"When the children were sleeping, I had to work. When I come back they wait for me with open arms and mouth wide open... So it's exciting. Fortunately, the show I am doing right now doesn't occupy too much of my time. I shoot three-to-four days in a week and rest of the time I spend with my babies," Karanvir said.
Karan is currently seen hosting Zee TV reality show 'India's Best Judwaah'. He was last seen with Mouni Roy in hit show 'Naagin 2'.
