Is your kid’s repetitive play a waste of time? A teacher and mom’s honest take
Last Wednesday, after back-to-back parent-teacher conferences, I was shoving a half-eaten granola bar into my bag when Leo’s mom pulled me aside by the classroom door. Leo, her quiet 4-year-old, had a smudge of blue tempera on the cuff of his dinosaur hoodie, and she was twisting his printed progress report between her fingers. “He spends almost 20 minutes every free play period just lining up his toy cars by the window,” she said, leaning in like she was sharing a secret. “My mother says it’s a waste of time. I should be making him join art or puzzles, right? Is this just… useless?”
I nodded, because I’ve had that exact conversation with my husband about our 7-year-old, Sam. Every single night before bed, Sam dumps his 10-pound bin of loose Legos onto the rug and sorts every brick by size, then by color, before he starts building whatever weird contraption he’s dreamed up that day. On school nights, we’re usually rushing: the kettle’s whistling for my tea, I still have to fold a load of laundry, my husband’s answering a last work email. Half the time, my husband will lean against the doorframe and mutter, “That’s such a waste of time. Why can’t he just grab the bricks he needs and go?”
I’d been watching Leo for three weeks by that point, so I told her what I’d seen. The first week, he just lined all the cars up end to end, all the way from the block shelf to the reading nook. The second week, he started splitting them into two lines: big cars and small cars. Last week, I knelt down next to him while he worked, and he pointed out every car that had four wheels versus six wheels, and told me which ones went to the airport and which ones went to the farm. He wasn’t just staring at cars. He was figuring out how to sort things, how to name categories, how to notice small differences. That’s not nothing—that’s the core of early math and science learning. Kids don’t learn classification from a worksheet. They learn it by moving things around and sorting them over and over.
I tested this with Sam a few months ago, after that conversation with Leo’s mom. One night, instead of rushing him after 5 minutes, I sat down on the rug next to him and asked what he was doing. He told me he got sick of digging through a messy bin mid-build, because it breaks his focus when he’s trying to plan his space station. The 15 minutes he spends sorting cuts down the time he spends digging by at least double, he said. I counted one night: he finished his whole build in 40 minutes, versus the hour it took when I rushed him to skip the sorting step. That’s not a waste of time. That’s problem-solving.
I used to think that any activity without a clear end product—a drawing to hang on the fridge, a finished puzzle, a read book to check off the homework list—was wasted. But I’ve started changing how I handle these moments, and it’s made things way less stressful for everyone. First, before I step in to stop anything, I spend 2 full minutes watching, not talking. I don’t jump in to redirect or suggest a “better” activity. Half the time, I’ll notice something I missed the first time: my son isn’t just messing around with Pokemon cards, he’s sorting them by hit points, which means he’s practicing ordering numbers, and then he reads the attack descriptions out loud, which is reading practice most kids won’t complain about.
Second, if the timing is bad—like when we have to leave for school in 10 minutes and he just started sorting his dinosaurs—I don’t say “that’s silly, stop it.” I say, “I see you’re working on sorting your dinosaurs right now. We have 2 more minutes to work on this, then we have to put them away. We can come back to it right after you get home from school.” It acknowledges that what he’s doing matters, it sets a clear boundary, and it doesn’t start a fight. I used to get way more pushback when I just told him to stop what he was doing.
Third, if the activity isn’t hurting anyone and it’s not messing with your schedule, just leave it alone. A lot of these repetitive, seemingly pointless activities are how kids calm down when their brains feel overloaded. I realized Leo lines up his cars right after circle time, when he’s just sat still for 15 minutes with 14 other noisy kids. That’s his way of settling his brain before he does anything else. His mom told me after that conference that he lines up his stuffed animals every night after family dinner, when the house is loud and chaotic. She never connected the dots before—he wasn’t wasting time, he was winding down for bed.
I still have days where I think it’s a waste. Last week, Sam spent 30 minutes sorting all his socks by color instead of putting them away like I asked, and we were late to soccer practice. I was annoyed the whole drive there. But on the way home, he told me he figured out he has 12 blue pairs and only 3 green pairs, so he needs more green socks for soccer. That’s not the outcome I wanted that afternoon, but it’s not nothing, either.
I don’t think we have to celebrate every single weird repetitive thing our kids do, or pretend it’s all some brilliant learning moment. Sometimes a kid just lining up cars is a kid lining up cars. But more often than not, the things we write off as a waste of time are just kid work we don’t understand yet. I still rush Sam sometimes, I still set timers and remind him we have places to be. But I’ve stopped asking if what he’s doing is useless. I just try to ask what he’s doing, first. Most of the time, the answer surprises me.
