Little Hazel has no choice but to become an older sibling, and Blunt has a foolproof way to make the transition appealing for her.

"My plan is just to tell her that this is less about having a sibling and more that she's being promoted," Blunt said. "She gets to have a worker now, you know, who she can boss around."

Blunt says this is "kind of a good tactic" and we can't help but agree with her. Parents out there who are planning on having a second child, take note.

Also, prepare yourself to maybe have one very bossy eldest child.
