Two moms in this week's "Teen Mom 2" Season 6 Episode 10 "Expect a Miracle" are embroiled in child custody and support issues.

In a sneak peek for Thursday's "Expect a Miracle," Chelsea Houska tells her friend Callie about a significant life decision.

"Cole is moving in ... soon," Houska says, as she and Callie swing on her daughter Aubree's swing set.

She explains that the original plan was for him to move in after the summer, but that his roommate is living out of their apartment, which will cause him to move. They are both breaking the lease.

"Is he excited?" Callie asks.

"Yes," answers Houska.

Houska says she explained to Cole DeBoer that the living situation will be like a family dynamic, and that she hopes he understands what he's getting into.

"He said 'I already thought about it and this is what I want,'" Houska says.

Callie agrees that he certainly seems committed to her and Aubree, especially considering "the attention he gives her ... he actually takes his time with her."

There is one issue, though, that concerns Houska.

"I don't know what to do about her wanting to call him daddy. That's really hard," she says.

Houska reveals that she looks forward to having a family.

"I've wanted a family since I had Aubree. Like, I tried to make it work with Adam for so long, but that wasn't it. I feel like this is all coming together with him," she says, referring to DeBoer.

Meanwhile, in the video clip for this week's episode, Jenelle Evans and her mother Barbara Evans argue over custody of Jace. Their attempt at mediation failed. Once again, mother and daughter meet at a restaurant to discuss an agreement.

"I don't think we're ever going to come to a resolution about Jace," Jenelle tells her mother, as her sons Kaiser and Jace eat.

Barbara suggests coming to an agreement about Jace visiting so that they don't have to go in front of the judge. She believes going to court will be "devastating."

"Because it may not be the answer you want to hear," Barbara warns, referring to a judge making the final decision. "You have got to give and take --"

"You do to," says Jenelle.

According to Barbara, at mediation she tried to talk with Jenelle about a plan, but Jenelle didn't want to hear it.

"You were flipping out," Barbara says.

"No, I said I want him every week and you get him on the weekends, or nothing at all," Jenelle says. "And then you said 'absolutely not.' And that's where we butted heads and said we can't solve this."

Barbara thinks it is harmful to "rip him out of everything that he's ever known," since she has had custody of the boy for most of his life.

"He's been staying with me every weekend for about two years now. So, how is that ripping him out --"

"Every weekend?" Barbara interrupts, exasperated.

"This isn't a competition who gets to spend more time with Jace because honestly, I should have him full time -- not you."

Barbara says she does not want to fight.

"You are not the mother or the father, you are just the grandmother," Jenelle tells her.

"I just want what's in the best interest of Jace," Barbara stresses.

"You want what's in the best interest of Barbara, so Barbara can control Jenelle," Jenelle says, and the video clip ends.

Kailyn Lowry-Marroquin wants ex Jo Rivera to pay more child support. She and husband Javi Marroquin meet Rivera at a park to talk about the issue.

"You don't want me to take you to court but we clearly cannot come to an agreement," she says to Rivera.

He responds, "You have to tell me what you are spending. What do you need from me?"

Lowry looks confused and asks, "What is going to happen from there?"

"We will sit down with the actual numbers and talk about what I can do and what I can't do," Rivera says.

Marroquin wants the child support issue to go before the court, which upsets Rivera.

"I guess you wouldn't understand unless you were actually in the situation," Rivera tells Marroquin.

Leah Messer finalizes her divorce from Jeremy Calvert. In a commercial for this week's episode, she is shown saying goodbye to twins, Ali and Aleeah Grace, and daughter, Adalyn, as she leaves for rehab.
