Speaking withEntertainment Tonightlast month, theBig Bang Theoryalum said that she’s going to “trust the process” when it comes to parenting her daughter on the way.

“I have no plan and I’ve read zero books so that’s the type of mom I will be,” she shared. “All the ways I’m not like a prepper. I’m just not that way. It’s gonna be great, I trust the process.”

As for Pelphrey, Cuoco said he is the opposite and has “googled enough for the both of us.”

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

Cuoco is excited to see herself and Pelphrey grow into their new roles as first-time parents, with sources recently telling PEOPLE she believes Pelphrey will be a “hands-on dad.”
