Kaley Cuoco may be in the third trimester of her pregnancy, but she has yet to pick up a parenting book.

“I’m not a prepper,” the “Flight Attendant” star told Entertainment Tonight on Wednesday. “I’m just not that way. … I trust the process.

“I’m just like, ‘It’s gonna be great,'” she continued. “But that’s how I’ve gone through life. I think nowadays we get so caught up. We didn’t even have all this stuff at our fingertips and now it’s almost too much.”

The actress, 37, recently spoke to a friend who said, “Your baby’s gonna tell you what to do.”

Cuoco “love[d]” that advice, gushing, “If this child is anything like me, she’s gonna be like, ‘This is what I want,’ and I just need to listen.”

She noted that her boyfriend, Tom Pelphrey, “has googled enough for the both of” them in recent months.

“He could probably deliver this baby at this point,” the “Big Bang Theory” alum joked.

The expectant star, who has “no plan and [has] read zero books,” is also expecting help from her “amazing” mom, Layne Ann Cuoco.

“She has honestly been waiting on a grandchild for, like, 20 years,” Kaley told the outlet. “She’s absolutely thrilled.”

She and Pelphrey, 40, went public with their pregnancy news in a October 2022 Instagram post, five months after making their relationship Instagram official.

“And then it was even MORE BETTER. 🎀🎀🎀,” the “Ozark” alum captioned photos of his girlfriend’s bump. “Love you more than ever.”

He and the Golden Globe nominee have continued documenting their journey before becoming parents, from a tropical babymoon in December 2022 to a baby shower the following month.

At their star-studded party in January, Kaley debuted a tattoo of her partner’s first name on her left hand’s ring finger.

The “8 Simple Rules” alum has been married twice before, wedding tennis pro Ryan Sweeting and equestrian Karl Cook in 2013 and 2018, respectively.

In April 2022, Kaley told Glamour that she will “never get married again.”

However, the Emmy nominee clarified that she “would love to have a long-lasting relationship or a partnership.”
