Scarlett Johansson is ''very lucky'' to be able to juggle work and parenthood.

The 30-year-old actress gave birth to daughter Rose - her first child with husband Romain Dauriac - seven months ago and admits her personal responsibilities mean she now has more to think about when choosing new roles, but she feels in a privileged position to have a job that means she can also see a lot of her little girl.

She 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.''

Scarlett can next be seen reprising her role as Black Widow in 'Avengers: Age of Ulton' and joked motherhood requires special kinds of superhero powers.

Speaking to 'Extra', she said:''Yeah, at 3am, 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.''

The actress recently teamed with co-stars Robert Downey Jr. and Chris Hemsworth for Jimmy Kimmel's game of 'Family Feud', where they were victorious against fellow 'Avengers' cast members Chris Evans, Jeremy Renner and Mark Ruffalo and she claims the group are all very competitive.

She joked: ''These guys are pretty competitive. You should see Chris Evans' running Charades game nights at his house; people get bloodied, it's out of control.''
