The 32-year-old actress welcomed Wyatt, her first child with husband Ashton Kutcher, 38, in October, 2014.
As she appeared at CinemaCon in Las Vegas to promote her new movie "Bad Moms", Kunis joked she struggles with the daring nature of her little girl, reported Us magazine.
"She's crazy. Kids are crazy," Kunis laughed.
"I don't really understand how they're all alive."
Kutcher recently appeared on "The Ellen DeGeneres Show" and spoke about his daughter, sharing a similar point of view to his wife as he explained.
"She tries to kill herself on a regular basis. Like, she doesn't realise that's a cliff and that could be dangerous. She'll just jump off the thing. She don't know yet. You'd think that they would come with instincts around fire and large falls, and they don't.
