"I am in no rush to become father... whenever she is ready (for it)," Saif told PTI in an interview here.
Kareena had recently said in an interview that she wants to become a mother but not in next two to three years.
Saif has two children -- Sara and Ibrahim -- from his former wife actress Amrita Singh.
Kareena, who married Saif in October 2012, is having a good run at the box office with the success of her latest release "Bajrangi Bhaijaan".
The "Phantom" actor said Kareena has managed to strike a fine balance between the blockbusters and small-budget films with meaty roles.
"I think it is important for her to balance with huge blockbuster films where she has nice small roles and with smaller budget films that are about her. She is doing that balance really well.. I am happy to see that," he said.
Saif said he likes to watch Kareena in romantic roles like the one she played in 2007 release "Jab We Met".
While Kareena bonds well with Saif's kids Ibrahim and Sara and has been often seen hanging out with them, the actor said he too share a good rapport with Kareena's sister Karisma and mother Babita.
"I don't think we would have got married if I wouldn't have had a great relationship with them. I am fond of her (Babita). She is an honest and down to earth person. I share a good relation with Karishma as well," he said.
The 45-year-old actor also revealed that his mother-in-law likes his romantic comedies like "Love Aaj Kal" and "Cocktail".
Saif said both his children are free to pursue their Bollywood dreams but only after completing studies.
"I think they both want to join films. Sara is doing well in studies but she has to complete her education first.. So, Sara first then Ibrahim. I want them to have a degree (first) and after that they can do whatever they want," he said.
