The couple shares two kids -- daughter Nysa and son Yug-- together, and the actress says keeping them away from the spotlight at large is an attempt to give the children their space where they are not bogged down by any kind of pressure.
"Ajay and I made a conscious decision to keep our children away from the media. We feel we want to keep them away from the pressure, from the unnecessary burden which will come on them. I don't want that to happen," Kajol says in an interview.
Kajol says their kids understand her and Ajay's profession since they were too small.
"Yug knows his father is an action star and he has done so many films. But at the end of the day, we have to explain to them that this is work, this is an outer personality which people look at us from the outside. We are your parents first and after that everything else."

Though her film appearances became sporadic, with only three full-fledged films, "My Name is Khan", "We are a Family" and "Dilwale" in the last seven years, Kajol says she never had to "sacrifice" her career for children.
"It is no sacrifice. I had children because I wanted to take their responsibility. It is really not a sacrifice, they are my top priority. Work is a part of my life and if God willing, it will forever be but my family, kids, they are life itself," she says.
It is a sequel to the 2014 comedy-drama "VIP" and stars Dhanush, Amala Paul, Vivek, Saranya Ponvannan and Samuthirakani returning from the first film.
