Talk about an anxious dad! While mother-to-be Mila Kunis prepares herself with frequent yoga sessions, her fiancé, Ashton Kutcher, is finding other ways to make sure the birth of his first child goes smoothly.

A source told E! Online that the 36-year-old actor has been making dry runs down to the hospital in order to see how long it takes them to get from there from their home.

"Ashton has made a couple dry-runs to the hospital to see exactly how long it will take them to get there," a source said about the "Two and a Half Men actor. "He's preparing for all scenarios and not leaving anything to chance. He wants everything to go smoothly!"

The couple is reportedly spending more time at home as the baby's due date gets closer, adding that "Mila's in the homestretch and they are both very excited. It could happen any day now."

"Ashton is not letting Mila out of his sight. They are spending every moment together," another insider told E! Online. "He can't wait."

The couple, who got engaged in February, have already decorated the nursery. An insider revealed that the actress is having a baby girl and is beyond excited. 

In an interview for the July issue of Marie Claire Magazine, the "Jupiter Ascending" actress said only her doctor and fiancée are allowed in the delivery room.

"Two people are allowed in my delivery room. My doctor and my significant other," she told the magazine. "And he is staying above the action. He'll be head to head. Not head to vag. Unless he wants to risk his life and see. But I wouldn't if I were him. I highly doubt he wants to see that being ripped apart and shredded. Because it will be shredded. It's just a matter of how badly."
