Filmmaker Kiran Rao, who became a mother to son Azaad last year in December, says she is not a perfect mother yet but is enjoying motherhood.

"I don't think I am perfect, but I certainly try and it's such a joy. I think every mother does what is best for her child because it's such a joy and a daily learning experience. So, I am enjoying it thoroughly.

I don't think I could have asked for more," the 38-year-old said here at the launch of painter Sangeeta Gupta's exhibition. Kiran made her directorial debut with "Dhobi Ghat" last year and the film won a lot of critical acclaim.
