"Kourt has been making sacrifices and refraining from business opportunities which would take her away from the children," a source told Hollywood Life. "She has also been going to counseling by herself regularly, something she wished Scott would do too. Meanwhile Scott is present for a week or month, on good behavior, only to routinely disappear the next."

After flying off to Dubai with Kim Kardashian earlier this month, Scott, 33, hopped on a plane to the Sundance Film Festival for a boys' trip, leaving Kourtney, 36, with their kids, Mason, 7, Penelope, 4, and two-year-old Reign.

“Kourtney is doing everything she can to provide a healthy family environment to her children, despite Scott’s periodic poor behavior," the source continued. "While Kourtney has remained committed to co-parenting their kids, she simply can’t say the same for her children’s constantly absent father."

Meanwhile, Kourtney was spotted out alone with her three kids on Tuesday, wearing an oversized bomber jacket, which has fans convinced the KUWTK star is hiding a baby bump.

The brunette beauty has been hinting at a pregnancy on social media non-stop over the last few weeks, even cradling one of her daughter's baby dolls.

Kourtney has made no secret of wanting a big family, and sources revealed to Life & Style exclusively that she has baby fever after getting back together with Scott over the holidays.

"You can see the chemistry between them again," a source said. "They flirt and she giggles and they make little inside jokes. It’s only a matter of time before No. 4 is on the way.”
