Barrymore, 39, and husband Will Kopelman welcomed daughter Frankie in April. The couple's baby girl joined older sister Olive, 2 and the actress said her family is her driving force, reported People magazine.
"It's amazing. It's the driving force behind how I live my life. The acting has to be less and less because it's too time-consuming. I love it and I don't want to abandon it, but it can't be at the forefront right now," she said.
