Soon-to-be-parents Mila Kunis and Ashton Kutcher are currently counting down the days until they welcome their baby girl into the world.

Kunis is now in her third trimester, which means her daughter is due soon in late August or early September. "She is scheduled to be delivering in less than 1 month and she cannot wait," a source very close to the 30-year-old actress told RadarOnline.

"Ashton has been excited every time we had a child actor on set," said the 36-year-old actor's "Two and a Half Men" co-star Jon Cryer. "He loves kids and could not be more stoked to have a child."

"Ashton and Mila are getting so excited," another insider told People. "Ashton is a kid at heart. He can't wait to do tons of stuff with the baby. [Mila] is feeling good and things are going smoothly. She does feel pretty big lately and can't do much because it's harder for her to move around."

Kutcher has been helpful to his fiancée, who has naturally slowed down her exercise routine from attending Pilates and spinning classes to just walking around in the neighborhood now. "Ashton does errands alone so Mila can stay home," the source revealed. "He seems to take great care of her!"

The "That '70s Show" stars, who are heavily involved in Kabbalah, do not plan to deliver their baby in the suggested method: "Mila was going to do an all-natural birth with no medications or sedatives, but she has been advised against this because she is such a small girl. Ashton will not accept this and refuses to see her in pain."

Once their first child is born, the couple plans to have another one. "She wants to get pregnant again right after this child is born, and she is cleared to do so by her doctor. She loved being pregnant and wants all of her children to be close in age," the source added. "They both want a big family and have been telling everyone this."

Mila Kunis and Ashton Kutcher, who got engaged in February, will get married next August.
