Drew Barrymore and her daughter, 9-week-old Olive Barrymore Kopelman, graced the Dec. 24 cover of People and in an interview with the magazine, the first time mother spoke about the experience of parenthood. 

On the cover, Barrymore is quoted saying that motherhood is "the coolest moment of my life" and she further talked about the home she wants to have with her daughter and art consultant Will Kopelman, whom she married in June.

"I really wanted a wonderful traditional home for my kid," she said. "Will comes from a strong family, he provides a strong family ... It just makes me so emotional because it's like a miracle."  

The 37-year-old described her responsibility as a mother, saying her biggest fear now is "How do I keep someone alive?" She did add that her and her husband sing "Good Morning" from the film "Singin' in the Rain" whenever they want Olive to smile.

The actress revealed in an earlier interview with Ellen DeGeneres that she got the idea for her daughter's name after she went for a sonogram and the doctor said at the time that the fetus was the size of an olive. 

"I was three months pregnant and they said your baby is the size of an olive, and that was it. We never looked back," she said.

DeGeneres then joked "It could have been the size of a peanut or a grapefruit."

Olive was born on Sept. 26. Barrymore and Kopelman have been together since 2011 and the actress was pregnant at their wedding ceremony. 

"I can't wait until I have my children," she told Haute Living. "I just want to build fun, great things for my family."

Barrymore was in one film in 2012: "Big Miracle" with John Krasinksi. Her last major motion picture before that was 2010's "Going the Distance," in which she developed an off-camera relationship with her co-star Justin Long.
