`Avengers: Age of Ultron` star Scarlett Johansson says she is "very lucky" to be able to juggle work and parenthood.

The 30-year-old who welcomed her daughter Rose -- her first child with husband Romain Dauriac -- seven months ago, says her personal responsibilities mean she now has more to think about when choosing new roles, reports femalefirst.co.uk.

Speaking on TV show `Extra`, Johansson said: "Maybe I'll be more discerning with the parts that I choose, because it takes me away from my home, but I'm very lucky I have a gig that I can kind of parent and work at the same time, for now, not many people get that."

Johansson, who will reprise her role as Black Widow in `Avengers: Age of Ulton`, said motherhood requires special kinds of superhero powers.

`Yeah, at 3 a.m., probably, when I'm like a heroic act, it's going to make me open my eyeballs and crawl into the other room continuously night after night,` she said.

`Avengers: Age of Ulton` will release in India on April 24.
