The 35-year-old actress and her filmmaker husband Paul W.S. Anderson already have a four-year-old daughter, Ever Garbo, but are keen to expand their family further, though they have no plans to do so in the near future.
She said: "We would love to haveanotherbaby but we take it organically, like we do everything.
"We do what we love to do. It happens when it happens. If it happens this year, then it happens this year. We are not planning on trying to get pregnant now, as we are preparing an action movie. After that, we`ll give it some thought."
Milla admitted being a mother has made her more cautious about doing her own stunts and curbed her adventurous streak.
She told Britain`s Hello! magazine: "I`m definitely a lot more aware of potential accidents. It`s funny, sometimes what you think looks super dangerous on screen is the safest stuff.
"I have done some pretty adventurous stuff in real life too, but not for a while. Definitely not since I became a parent."
