If you’ve followed the Teen Mom franchise since the early 2010s, you probably feel like you’ve watched Aliannah, Aleeah, and Adalynn grow up in your own living room. It’s wild. One minute they’re toddlers causing chaos in the backseat of a car in rural West Virginia, and the next, they’re basically adults.
Honestly, the transformation is staggering.
In 2026, Leah Messer daughters aren't those little kids from the "16 and Pregnant" days anymore. They are navigating high school, dealing with serious health challenges, and carving out identities that have nothing to do with MTV cameras. But with that fame comes a lot of misinformation. People see a 15-second Instagram clip and think they know the whole story. They don't.
The Reality of Raising Aliannah and Aleeah in 2026
The twins, Aliannah "Ali" Hope and Aleeah "Gracie" Grace, turned 16 in late 2025. Yeah, let that sink in. They are officially in the "Sweet 16" era.

While most teens are just worried about homecoming or passing their driver's test, the dynamic between the twins is way more complex. Ali and Aleeah are fraternal twins, and they couldn’t be more different. Aleeah has always been the high-energy, outspoken cheerleader type. She looks so much like Leah it’s actually kind of spooky—fans call her Leah’s "clone" for a reason.
But Ali’s journey has been defined by something much heavier: Titin Myotonic Muscular Dystrophy.
The Wheelchair Debate: Independence vs. Safety
Recent episodes of Teen Mom: The Next Chapter have shown a lot of tension regarding Ali’s mobility. It’s a touchy subject. Basically, as Ali has entered high school, she’s pushed for more independence. She wants to walk. She wants to be like every other kid in the hallway.
Leah and Corey Simms (the twins' father) have been caught in that impossible parenting trap. Do you force your teenager to use a wheelchair to preserve her muscle strength, or do you let her walk and risk a fall or faster muscle deterioration?
- The Conflict: Ali often resists using her power chair for long distances at school or sporting events.
- The Risk: Overworking her muscles can cause irreversible damage.
- The Result: There have been some pretty raw, tearful moments on screen where Leah has had to "let go" and let Ali make her own choices, even when they’re scary.
Ali is incredibly strong-willed. In 2025, she officially got her learner’s permit, a milestone many thought might be a struggle given her condition. She’s proving people wrong daily.

Then there’s Addie. Adalynn Faith Calvert.

If you’ve watched even five minutes of the show, you know Addie has always been the "sassy" one. She’s now 12 (turning 13 in early 2026), and that personality hasn't dimmed down one bit. She’s the daughter of Leah’s second ex-husband, Jeremy Calvert.
While the twins are navigating the heavy stuff of mid-high school, Addie is entering those "tween" years where everything is a big deal. She’s still the life of the party, but Leah has shared that Addie is also a huge support system for her older sisters.
The co-parenting dynamic with Jeremy is... well, it’s better than it used to be. They’ve had their massive blowups over the years, but they’ve stayed relatively civil for Addie’s sake lately. It’s not perfect, but it’s functional.
What People Get Wrong About Leah’s Parenting
People love to judge. That’s just the internet.
One of the biggest misconceptions about Leah Messer daughters is that their lives are just one big reality TV show. In reality, Leah has been much more protective of their private lives in recent years. She’s been open about her past struggles with addiction to painkillers—an addiction that started after Addie’s birth—and she uses those "mistakes" as teaching moments for the girls.
Some fans think she’s "smothering" them or talking about her past too much. But if you live in West Virginia, you know the opioid crisis is no joke. Leah is basically trying to "armor" her girls against the things that nearly took her down.
The Health Updates
Ali’s health is a frequent search topic. It’s important to clarify: Muscular Dystrophy is progressive. There isn't a "cure" yet, but Ali has shown remarkable resilience. Her doctors, including the well-known Dr. Tsao, have noted that her strength in her "mind and body" is better than expected at this stage. Much of this is credited to her physical therapy and her love for horseback riding, which helps with core strength and balance.

So, what’s next?

The twins are looking at colleges. That’s a sentence that feels weird to type. Aleeah is still very much into the cheer scene and social media, while Ali is focusing on advocacy and her own unique path. Addie is just beginning to find her own lane outside of being the "little sister."
Leah’s focus in 2026 is clearly on building a "foundation." She’s single, she’s working on her own career goals, and she’s trying to ensure her daughters don't repeat the cycle of teen parenthood that she started.
Actionable Insights for Fans and Parents
If you’re following the journey of the Messer family, there are a few things to keep in mind regarding their 2026 status:
- Respect the Boundaries: While they are on TV, these are real teenagers navigating real-world insecurities.
- Support MD Awareness: Ali’s specific type of Muscular Dystrophy is rare. Learning about the Titin gene can help you understand why her journey is different from others with MD.
- Co-parenting is a Marathon: Leah, Corey, and Jeremy haven't always gotten it right, but their current "united front" for the girls' big milestones (like driving and high school sports) is a blueprint for high-conflict families trying to do better.
The story of Leah Messer daughters is no longer just a "Teen Mom" subplot. It’s a story about three distinct young women growing up under a microscope and somehow coming out the other side with their own voices.
Keep an eye on Ali’s advocacy work—she’s likely to become a major voice for disability rights as she enters her late teens. And Aleeah? She’s probably going to surprise everyone with a career that goes way beyond reality TV. As for Addie, she’s probably still going to be making us laugh for years to come.
