It’s a Tuesday morning, and you’re scrolling through Instagram, looking for the usual: tips on how to stop your toddler from throwing a shoe at the dog or maybe a way to make bedtime less of a gladiatorial match. You see Mandy Grass, the face behind The Family Behaviorist, and she’s her usual composed self—straightforward, clinical yet kind, and deeply practical. But lately, if you’ve been paying attention to the subtext of her posts or the long-form interviews she’s done recently, you might have noticed a shift.
The internet is a funny place. People feel like they know Mandy because she’s been in their ears and on their screens, helping them navigate the messiest parts of parenting for years. So, when the word "divorce" starts circling around a public figure whose entire brand is built on family dynamics, the questions come fast. Honestly, it’s not just about curiosity. For a lot of her followers, it’s about "If the expert’s family structure is changing, what does that mean for the advice she gives me?"
The Reality Behind the Rumors
Let’s get the facts straight because there’s been a lot of "he-said, she-said" in the comments sections of parenting subreddits. Mandy Grass, a Board Certified Behavior Analyst (BCBA) and a powerhouse in the parenting coaching world, has transitioned into life as a solo parent.
She hasn't made a giant, "Life Update: We’re Splitting" post with a black-and-white photo of a sunset. That’s not really her style. Instead, she’s been incredibly candid in podcast appearances and specific social media clips about her new reality. In a 2025 interview, she spoke openly about navigating parenting post-divorce and the weight of being a solo parent to three girls.
It’s a massive shift. One day you’re part of a two-parent system, and the next, you’re the primary person navigating ADHD symptoms, school transitions, and the "four functions of behavior" all on your own.
Why the Mandy Grass Divorce Discourse Matters
Most people follow Mandy because she doesn't do "fluff." She gives you the "if-then" of parenting. If your kid hits, then you do this. If your kid won't eat, then we try that.

When the news of her divorce became public knowledge among her core community, it actually added a layer of E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) that you can’t get from a textbook. She isn't just a BCBA who studied behavior in a lab or a classroom. She’s a mom who is now applying those same rigorous behavioral strategies to a high-stress, high-emotion life change.
Here is what Mandy has actually shared about the process:
- Solo Parenting is Different: She has been vocal about the fact that "solo parenting" and "co-parenting" are two very different animals.
- Name Without Blame: One of her core concepts is repairing after a parenting misstep. She’s applied this to the divorce context—teaching her kids (and her followers) how to talk about big changes without casting someone as the villain.
- The "Ick" List and Moving On: While she keeps the private details of her former marriage private—as she should—she has referenced resources that helped her, including podcasts like The Mel Robbins Podcast and experts like Natalie Hoffman, who focuses on Christian women in difficult relationships.
Addressing the "Expert" Double Standard
There’s this weird thing we do where we expect parenting experts to have "perfect" lives. If a nutritionist eats a donut, we feel betrayed. If a behaviorist gets a divorce, we wonder if the "system" failed.
But if you look at Mandy’s work, the "system" is exactly what’s keeping her afloat. She’s used the same visual schedules and reinforcement systems she teaches to keep her household running while she navigates the emotional fallout of a legal separation.
Actually, it’s kinda refreshing.

In a world of filtered perfection, seeing an expert say, "Hey, my life looks different now, and it’s hard, but these tools still work," is way more valuable than a curated highlight reel. She’s emphasized that our kids often save their hardest emotions for us—the "safe" parent. When a divorce happens, those emotions explode. Mandy’s approach has been to use empathy mixed with very clear, firm boundaries.
What This Means for The Family Behaviorist Brand
If you’re worried that the Mandy Grass you know is going to disappear into a cloud of "vague-blogging," don’t be. If anything, her content has become more grounded.
She’s still focused on:
- The Four Functions of Behavior: (Escape, Attention, Tangible, Sensory).
- Visual Schedules: Because kids in two-home households need predictability more than anyone.
- Technology Contracts: Keeping kids safe online, which is even harder when you’re out-numbered.
How to Navigate Your Own Family Shifts (Mandy-Style)
If you’re in the same boat—maybe you’re going through a divorce or you’re suddenly solo parenting—there are a few actionable takeaways from Mandy’s public journey that you can use tonight.
Stop Avoiding Transitions
Mandy often talks about how transitions are where the wheels fall off. If your kids are moving between houses, don't make the "hand-off" a big, emotional production. Keep it clinical. Keep it boring.

The Power of "Okay, Mommy"
She taught her kids the replacement behavior of saying "Okay, Mommy" when they hear the word "no." This doesn't stop being effective just because you’re in a different house. Consistency is the only thing that beats the chaos of a divorce.
Repair, Repair, Repair
You’re going to lose your cool. You’re going to be tired because you’re doing the work of two people. When you snap, use the "name without blame" technique. "I was frustrated because I’m tired, and I shouldn't have yelled. Let’s try that again."
Final Thoughts on the Change
Mandy Grass isn't a different person because she’s divorced. She’s just a person with more data now. She’s seeing how behavior analysis works in the trenches of a life-altering event.
Honestly, the "Mandy Grass divorce" isn't a scandal. It’s a case study in resilience. It’s proof that the tools she’s been selling for $175 an hour or in her digital courses aren't just for the "easy" times. They are for the times when you feel like you’re barely holding it together.
Next Steps for You:
- Audit your transitions: If your kids are struggling with the back-and-forth between houses, look at Mandy’s "Visual Schedules" guide.
- Check the "Four Functions": Before you get mad at a post-divorce tantrum, ask yourself if the child is trying to escape a feeling or get attention they feel they’re losing.
- Follow the pod: Listen to Mandy’s guest appearance on the Accidental Experts podcast from late 2025 for her most raw take on solo parenting.
Focus on the behavior you can see, not the "why" you can't control. That’s the most Mandy Grass advice there is.
