Kellie Martin, who starred in the 1989-93 series Life Goes On and then later on ER, and her husband, Keith Christian, are expecting their first child in October.
Martin, 30, had better be a quick study. "I never even babysat," she tells the Associated Press. "The only time I've changed a diaper is when my friend, who just had a baby, called and said, 'Come over, you need to practice.'"
The actress, however, did manage some hands-on experience with an infant in her latest role – set to air Saturday – as amateur sleuth Samantha Kinsey on the Hallmark Channel's Mystery Movies. In the episode, Kinsey ends up caring for a suspect's infant – actually played in the movie by 6-month-old triplet boys.
Says Martin: "I looked at the mother, who was taking care of these three little babies, and I thought, 'I can't imagine how demanding that must be. I'm just going to get one. Yeah, I can do this!'"
