Understanding the two nervous system patterns I see most often in children — including my own.

I have one kid who hears a three-word instruction and somehow processes absolutely none of it. And another who is mentally preparing for every possible catastrophic outcome before we’ve even left the driveway.

For the longest time, I thought these were just personality differences. One was “sensitive.” One was “laid back.” One worried too much. One couldn’t focus to save his life.

Now? I see two very different nervous system patterns.

Some kids are hyper-aroused. Their systems are constantly scanning for stress, overstimulation, danger, change, discomfort — basically life itself. These are often the anxious kids, the perfectionists, the overthinkers, the kids whose fear can completely get the best of them, the ones who need everything in its place, and somehow ask 47 questions between school pickup and home. They’re also usually the kids who have the hardest time winding down at night because their brains simply do not know how to turn off.

Then there are the hypo-aroused kids. The foggy ones. The checked-out ones. The kids who seem exhausted by existing. Hard to wake, hard to motivate, struggling to focus, emotionally flat sometimes. These kids are often quickly labeled as lazy, unmotivated, defiant, or “just not trying hard enough” — until they suddenly explode emotionally and end up getting themselves in trouble when they lose control of their emotions. But underneath it, they’re struggling too.

Different behaviors. Same underlying story: a nervous system that isn’t functioning in balance.

And honestly, once I started understanding the connection between the brain, body, and nervous system, my kids started making a lot more sense to me. Behavior, mood, focus, sleep, emotional regulation — they’re not isolated issues. They’re connected expressions of how a child’s system is functioning underneath the surface.

The good news? You don’t need to become a full-time nervous system detective overnight (although apparently, I accidentally did). Sometimes the biggest shifts come from the lowest hanging fruit: improving sleep, stabilizing blood sugar, reducing overstimulation, supporting gut health, getting kids outside more, and creating more predictable rhythms at home.

Small shifts help the system feel safer. And safer systems function optimally. 

This work became my obsession because these aren’t hypothetical children to me.

They’re mine.
