The "Saving Mr. Banks" star, who is mother to a 26-year-old adopted son and a teenage daughter, took a year off from acting to concentrate on perfecting her parenting, and now she's encouraging other working mothers to follow her example.
She tells Britain's Daily Mail, "You can't be a great mum and keep working all the time."
Thompson tells the publication her year away from Hollywood was "a birthday present to myself," adding, "I didn't actually act or write. I was just a mum. ... I taught drama at my daughter's school, cooked meals and had fun.
"I highly recommend others to do the same if they can afford it. ... Motherhood is a full-time job. The only way I could have continued working would have been by delegating the running of the home to other people. I never wanted to do this, as I find motherhood profoundly enjoyable."
