Why Does My Kid Talk About The Same Thing Over And Over? Tips For Repeating Obsessive Conversations In Children
“Mom, did you know T-Rex teeth are almost 12 inches long? That’s longer than my arm.” Seven-year-old Eli kicked the back of my driver’s seat, crumbs of cheddar goldfish falling into the gap between the console and the seat. It was 3:15 on a rainy Tuesday, I’d just picked him up from second grade, and that was the fourth time he’d said that exact sentence in 24 hours.
I sighed, checked the traffic ahead, and said, “Buddy, I remember. You told me when we woke up this morning.”
“Did I? Did I tell you what would happen if a T-Rex got into the Kroger parking lot?” he asked, leaning forward between the seats. And off he went again, same details, same question at the end about whether we’d hide in the frozen food aisle or the car. By the time we got home, I was grinding my teeth. That night, after I got him to bed, I sat on the couch scrolling Google at 10 o’clock, searching “obsessive conversations in kids” wondering if this was something I needed to worry about.
Then I remembered Leo, a first grader I had in my class two years ago. Every single circle time, no matter what we were talking about—shapes, the class hamster, a field trip to the apple orchard—Leo would interrupt to talk about jet engine turbines. He’d corner other kids at recess, he’d pull me aside during centers to go through the same three facts about how jet fuel works. I was new to teaching back then, I thought it was odd, I referred him to our school psychologist to get checked out.
What she told me stuck with me, even before Eli went through this T-Rex phase. She said most repetitive conversations aren’t the big, scary thing parents and teachers usually worry about. It’s not automatically OCD, it’s not a sign something’s wrong. For kids, their brains are built to latch on hard to new things that fascinate them. Their working memory is a lot smaller than ours—so when something that exciting takes up almost all the space in there, it can’t just sit. It has to come out, over and over, until it settles. It’s not that they don’t remember they already told you. It’s that they can’t think of anything else to say, or they’re still working through how cool (or scary, or confusing) it is, so they say it again.
After that chat with the psychologist, we tried a few small things with Leo that ended up working. I tried those same things with Eli, and they worked here too, so I’ve started sharing them with parents who email me about the same thing.
The first thing is to give the obsession a specific time and place, instead of letting it take over the whole day. It sounds simple, but it’s way easier than redirecting 10 times an hour. With Eli, I sat down with him after breakfast one day and said, “I love hearing about T-Rex so much. It’s so cool how big his teeth are. Let’s set aside 10 minutes right after dinner every single night this week for all your T-Rex facts. When we’re in the car, or at dinner before that 10 minutes, we’ll talk about other things, okay? If you think of a fact before then, you can write it down in your dinosaur notebook to save it.” We got a cheap spiral notebook from the dollar store, and he drew T-Rex teeth on the cover with a red crayon. The first day, he still slipped up twice in the car, but I just tapped my watch, and he grinned and grabbed his notebook to scribble the fact down. No fight, no me getting annoyed.
The second thing is don’t shame them for it, and don’t just keep saying “we already talked about this.” When I did that at first, it just made Eli more determined to say it again—he thought I didn’t hear him right the first time, so he had to tell me again. A quick gentle reminder of the chat time is way better than a frustrated rebuke. When we’re around other people, like at a family barbecue or a playdate, I step in early instead of letting it get awkward. If he starts telling my aunt about T-Rex teeth when she’s asking him about his soccer game, I’ll say “Eli has the coolest T-Rex fact he’s been dying to tell everyone, let’s let Aunt Marnie hear about soccer first, then you can tell her after dinner, okay?” It redirects without shutting him down, and no one feels bad.
Of course, it’s okay to worry. I still check in with myself sometimes—what if this doesn’t go away? The psychologist told me when to pay closer attention: if your kid stops doing all the things they used to love, if they can’t focus on anything at all even during their favorite activities, if the repeated conversations are all about calming a really big fear (like asking 10 times a day if our family is going to get sick) that doesn’t go away after a couple weeks. That’s when you talk to your pediatrician or a child psychologist. But nine times out of ten, it’s just a phase.
I also learned it’s okay to set small boundaries for your own sanity. If I’m on a work call and Eli pops in to tell me a T-Rex fact, I’ll wave him to the notebook and mouth “after dinner” and that’s that. I don’t feel guilty for not dropping everything to listen to the same fact for the fifth time that day, and he doesn’t feel rejected.
It’s been six weeks since the T-Rex phase started. We still have our 10 minute T-Rex chat after dinner most nights. But this week, Eli spent three of those chats talking about the new Lego spaceship he wants for his birthday, instead of dinosaurs. Yesterday, on the way to school, he talked about how the frost looked on the grass for 12 minutes straight, no T-Rex mentions at all. It’s fading, slow, not all at once. I don’t know what he’s going to latch onto next—probably sharks, or volcanoes, something equally loud and repetitive. But I don’t panic anymore. It’s just how their brains work, right? They find something that lights them up, and they have to share it, over and over, until it sticks.
