Los Angeles: Actress Mila Kunis, who is preparing to welcome her second child with actor Ashton Kutcher, says she has discovered that "children are f**king crazy". In an interview with Glamour magazine, the actress reflected on her first pregnancy with the couple's daughter, Wyatt Isabelle, born in October 2014, and how she got ready to have a baby, reports etonline.com. "They are also suicidal. Like, at the park, certain jungle gyms have an opening for older kids to jump out of. (Wyatt is) 19 months; she can't jump. She just walks off it as if she is on a pirate ship," Kunis told the magazine. "Another important thing to learn is that kids have a personality that has nothing to do with you. I have a really sweet daughter. She wants to hug all the other kids. I didn’t teach her to be sweet. It has nothing to do with me. I have realised you can control only so much," she added. The 32-year-old actress has also learned a lot about her husband in their years together, including the look on his face when he is not telling her the truth. "We can't bulls**t each other. I literally can't lie to him. He can call me out on everything, and I can do the same, because there is nothing about the other person's face that we don't know," Kunis explained. "We know when they are acting, thus we know when they are lying," she added. Kunis will next be seen in the comedy film "Bad Moms". Directed and written by Jon Lucas and Scott Moore, the film also stars Christina Applegate, Kristen Bell, Kathryn Hahn, Annie Mumolo and Jada Pinkett Smith.
