For PASSIONS' Justin and Lindsay Hartley (Fox and Theresa), time is definitely flying by when they're having fun — with their daughter, Isabella.

"She's going to be 9 months, I can't believe it," enthuses Lindsay. "She's starting to make Dada and Mama sounds. She doesn't know what she's saying just yet, but I can't wait for her to [be able to speak]. I want to hear what she has to say!

"Watching a baby grow is fascinating," continues Lindsay. "She's truly becoming her own person. Before you know it, they're walking and talking and having opinions. Even their natural instincts: Like she can pick up and eat Cheerios on her own, and nobody told her, 'Isabella, you pick up the Cheerio and you put it in your mouth and then you chew it.' It's the coolest thing. Even crawling. Who taught them to crawl? They just do. That's why they say it's a miracle."
