Overwhelmed new mom Drew Barrymore has her hands full with a new baby and a toddler, and Breaking Celebrity News has exclusively learned that she’s turned to her good friend Christina Applegate for helpful baby advice.

Since Barrymore, 39, gave birth to her second daughter, Frankie, on April 22, the former Married with Children star has put the Blended actress through "a mini boot camp on the most basic things relating to child care," a source told Radar.

While Barrymore, 39, is also raising Olive, 20 months, with her art consultant husband Will Kopelman, she’s turning to Applegate for mommy guidance.

"Drew is relying on her fellow mom pals to help her cope with adjusting to having two kids," the source said. “It’s finally hit home to Drew that she'll have double the work, but she's still refusing to hire a nanny."

According to the source, after busy actress-turned-movie-producer Barrymore gave birth to Olive, "She moved her office to her Los Angeles home so she could focus on being a full time mom. But as her own parents John Drew and Jaid weren't nurturing, Drew was never comfortable relying on her own mother at all for advice and has said that they're estranged. So instead, she's leaned heavily on friends like Christina who already have parenting experience.â€
