Barrymore, 38, is expecting her second child with art consultant husband Will Kopelman, reported Us magazine.
"I read her a lot of books. She loves books! That's her favorite thing in the world, books. She is 14 months so it's as much as she can grasp but she definitely gets it. She points to my stomach and says baby. How cool is that?," she said.
Though Barrymore admits of being more relaxed this time around, but says there is still the stress of being a working mother.
