What Is Proprioception — And Why Your Toddler Needs to Crash Into Things
Your kid isn't being wild. Their body is asking for something specific — and once you understand what, everything starts to make a little more sense.
I didn't learn about proprioception in a formal class. I learned about it the way a lot of us learn the things that actually stick — because I needed to. I grew up with ADHD, dyslexia, and a body that often felt like it was operating on a different frequency than everyone else's. When I started working in early childhood and met kids whose behavior was being labeled as "challenging" or "disruptive," something in me recognized them. Not because I had all the answers, but because I'd been one of them.
I started reading. Studies, articles, books by occupational therapists and sensory integration specialists. I'm not a clinician — I want to be clear about that. But I'm a person who has lived in a sensory-seeking body, worked with children whose needs weren't being fully seen, and is now raising two kids of my own who crash into furniture, beg to be squeezed, spin until dizzy, and ask to be held upside down like it's their job.
So when I say this: your toddler isn't being wild. Their body is asking for something. And proprioception is probably part of what it's asking for.
So what actually is proprioception?
Proprioception is your body's sense of where it is in space. It's sometimes called the "hidden sense" because unlike sight or hearing, you can't really point to where it comes from — it's everywhere. It lives in your muscles, joints, and tendons, and it sends constant signals to your brain: how much force you're using, where your limbs are, how hard you're pressing, whether you're moving or still.
When you reach into a bag without looking and find your keys, that's proprioception. When you climb stairs in the dark without thinking about it, that's proprioception. When you pick up a paper cup without crushing it, that's your proprioceptive system calibrating the exact right amount of force.
Children — especially toddlers — are still building this system. Their proprioceptive sense is developing rapidly, and some kids need more input than others to feel regulated, grounded, and ready to engage. These are the kids we call sensory seekers. And crashing, bumping, squeezing, and jumping? That's not misbehavior. That's their nervous system doing its job and asking for what it needs.
What proprioceptive seeking actually looks like
My oldest spins. Not a little twirl — full, committed spinning until he's dizzy, and then he does it again. He crashes into the couch cushions with his whole body. He asks to be squeezed tight, especially when he's overwhelmed. He loves being upside down. He bumps into me constantly — not accidentally, intentionally, like a reminder that he's there and his body is real.
My youngest is still little but already showing the same patterns. The heavy play. The need for deep pressure. The way being held tight is the thing that calms him when nothing else will.
In the children I've worked with, it looked like the kid who couldn't sit at circle time without rolling around on the floor — not because he was defiant, but because his body was desperately trying to get the input it needed to pay attention. The one who would run full speed into the wall and then be perfectly calm for the next twenty minutes. The one who chewed everything — pencils, shirt collars, anything — because her mouth was seeking proprioceptive input too.
Crashing into furniture, walls, or people intentionally
Wanting to be squeezed, wrapped tightly, or held with firm pressure
Spinning, rolling, or tumbling — and wanting more even after getting dizzy
Loving to be upside down or hanging
Stomping, jumping, or running more than seems necessary
Chewing non-food items (this is oral proprioception)
Seeming to use too much force — hugs that are too hard, touching things more firmly than needed
Why "just stop them" doesn't work
Here's the thing that changed how I respond to my kids' sensory seeking: when a child's proprioceptive system is under-stimulated, their nervous system is essentially dysregulated. They cannot focus, sit still, listen, or engage meaningfully until that need is met. Telling them to stop is like telling someone who's starving to just stop thinking about food.
It's not a discipline problem. It's a sensory need. And when we understand it that way, our whole approach shifts — from trying to stop the behavior to finding safe, appropriate ways to meet the need underneath it.
This was the part that felt so obvious once I understood it, and so frustrating that it wasn't being talked about more. In the classroom I worked in, kids were being redirected away from the very things their bodies were asking for — and then struggling to engage with anything else because the need was still unmet. When we started building heavy work and movement breaks into the day intentionally, everything changed.
Heavy work — the thing that actually helps
Occupational therapists use the term "heavy work" to describe activities that give the muscles and joints that deep proprioceptive input. It's one of the most effective tools for helping sensory seekers regulate — and most of it requires zero equipment and costs nothing.
- Carry heavy things — a backpack with some books in it, a bag of groceries, a laundry basket. Make them the helper.
- Push and pull — pushing a full laundry basket, pulling a wagon, moving dining chairs to sweep.
- Climb — climbing structures, couch cushion obstacle courses, or just climbing you.
- Wheelbarrow walking — hold their ankles while they walk on their hands. Kids go wild for this.
- Wall push-ups or pushing against a wall — surprisingly satisfying for the proprioceptive system.
- Rough and tumble play — wrestling, pillow fights, rolling around together. Yes, it's chaotic. It's also deeply regulating.
- Tight squeezes and bear hugs — deep pressure is proprioceptive input. When your kid asks to be squeezed, that's a direct request from their nervous system.
- Jumping on a trampoline or couch cushions on the floor — repetitive jumping is one of the most efficient proprioceptive inputs there is.
- Playdough and sensory bins — squeezing, pressing, and manipulating playdough provides quieter proprioceptive input — great for at the table.
The goal isn't to tire them out (though that's sometimes a welcome side effect). The goal is to fill the proprioceptive tank so their nervous system can settle into a regulated state. For many sensory-seeking kids, ten minutes of intentional heavy work before a quiet activity makes that quiet activity actually possible.
A note on sensory processing differences
Some children have sensory processing differences that go beyond typical development — including sensory processing disorder, autism, ADHD, and other diagnoses that affect how the nervous system receives and responds to input. If your child's sensory seeking feels intense, is significantly affecting daily life, or you have concerns beyond what you're reading here, please reach out to your pediatrician or ask for a referral to an occupational therapist who specializes in sensory integration.
This post is a starting point, not a diagnosis. It's the kind of information I wish someone had handed me earlier — as a parent, as an educator, and as someone who has navigated my own sensory differences my whole life. Understanding proprioception doesn't solve everything. But it changes the lens. And sometimes that's everything.
Your kid who crashes into things isn't out of control. They're communicating. And now you speak a little more of their language.
