"After we had Wyatt, the second I gave birth, I knew we had to have another baby," she admitted. "We both knew it, we just felt it."
She continued, "And so I always say after the second one, we'll know if we need to have another one. I really do believe you know when your family is complete."
Mila also dished about her new movie and why everyone—not just moms—can appreciate it.
"I really think it's a movie for everybody," she said. "Yes, women that are mothers can relate to it for sure, but you do not have to be a mom to appreciate this movie at all. I think if you're a guy, maybe you'll appreciate your mom a little more or understand your wife a little more."
