Toddlers say the darnedest things — and 21-month-old Wyatt Isabelle Kutcher is no exception.

“When you tell a kid that you have a baby in your belly, they think everyone’s got a baby in their belly, so my daughter will be like, ‘Where’s the baby?’ ” Mila Kunis told Extra on Monday at the N.Y.C. premiere of her new comedy Bad Moms.

And the big sister-to-be doesn’t stop at just asking Mom all the hard-hitting questions.

“She’ll point to her belly, she’ll point to your belly, a stranger’s belly,” Kunis, 32, continues. “So there’s a slight problem because she’s not quite old enough to understand, so she’s like, ‘Everybody has a baby in their belly.’ ”

Kunis and husband Ashton Kutcher, 38, just celebrated their first wedding anniversary. They are expecting their second child, Kunis’ rep confirmed exclusively to PEOPLE in June.

Aside from the ways being a mom has changed her general outlook on life, the expectant actress also notes that having a solid support system is crucial in a world where she’s juggling parenting and a hectic work schedule.

“Acting is like 17-hour days, it’s not a nine to five,” Kunis says. “Having the script and having the amazing group of women that I worked with [on Bad Moms], besides my husband who is super supportive, it was the greatest experience that made me realize how important it is to be fulfilled as a human being in order to be fulfilled as a mother.”

Though the film, which premieres in theaters July 29, pokes fun at the idea of having to be a “perfect” mother 24/7, Kunis admits that real-life mothering has its scary moments — like the time she forgot one crucial detail while taking a car trip with her daughter.

“I look in my rearview mirror and [Wyatt’s] not strapped in,” she confesses. “I pulled over and I strapped her in … I got to my husband’s work, completely broke down, and started crying.”
