Last week, viewers saw Kylie agree to give husband David (Jack P Shepherd) a child of his own, but upcoming episodes show that she is deceiving him by continuing to take contraceptive pills.
Speaking to Inside Soap, Lane explained that Kylie's new job at the Bistro with David's half-brother Nick (Ben Price) has made her reconsider what she currently wants from life.
Lane commented: "The problem is that Kylie has always leant on David, but now she's got a career of her own, that's all changed. She's more independent, so he probably feels like she doesn't need him as much.
"Perhaps David is now looking towards fatherhood because all of Kylie's attention is focused on work instead of him."
She continued: "I'd love Kylie to make a huge success of the Bistro. She has all these quirky ideas that really shine through. Nick is amazed by what she's capable of, so who knows?
"If David gave her an ultimatum, she'd be inclined to choose her career over being a mum again - but only in the hope that he'd change his mind and agree to wait until she's ready to have a baby."
As Kylie is eventually honest with David about not wanting a baby yet, Lane added that she hopes the couple can settle their differences.
She said: "I think they're capable of getting through a lot. People are often against them and think their marriage won't last. There's been a lot of doubt about them as a couple, but they've never doubted themselves."
