Teen Mom's Aleeah Simms Tells Mom Leah Messer Why She Wanted Twin Aliannah to Get Her Learner’s Permit First

On the Thursday, April 24 episode of Teen Mom: The Next Chapter, the proud mom checks in on daughter Aleeah after she decides she isn't ready to take her permit test at the same time as twin sister Aliannah. Both girls had failed the test on the first attempt.

As Leah checks in on the studying Aleeah, she asks, "I know we're excited for Ali, but is there any more to this?"

"Well, yeah. I wanted her to have it first," Aleeah admits. "Because she has worked hard for it. Ali wants this bad. She wants to drive. If I would have got it before her, and she wanted it more, I feel like that would have bothered her. I didn't want that to bother her."

"You don't have to hold yourself back either. You know that, right?" Leah asks.

"I know," Aleeah confirms. "I'm choosing to hold myself back, just for a little bit. Not for long."

"I think that it's important that you don't hold yourself back. But I do think that this is something that is very selfless and kind of you," Leah acknowledges.

"I just feel like I have all my moments, and now, she just wants her own," Aleeah explains.

"That's very sweet of you. But milestones, they look different although you are twins. I think that's important to remember," Leah says, adding, "I acknowledge you and I love you, study up."

In a confessional, Leah shares, "When I see my daughters look out for each other, for example, the exam, I think it's beautiful."

"I think Aleeah wants Ali to have her moments because she's her sister's keeper. I think it just shows how good of a heart Aleeah truly has and how much she cares and loves her sister," she continues. "They just have each other's back like no other."

The previous episode showed just what it took to get Ali, who lives with muscular dystrophy, cleared to drive. Leah explained to her own sister, Victoria, why the situation was so emotional after years of special accommodations for Ali.

"I just want to go through whatever they tell us with [her], because I just want to have a relationship with her and it not always be surrounded around medical stuff," Leah said ahead of the final decision.

Tearfully, she continued, "I just want to be your mom and I want to support you, whatever that looks like."

Teen Mom: The Next Chapter airs on Thursdays at 8 p.m. ET on MTV.
