Why Your Tween Makes Decisions That Confuse You — And What's Really Going On Inside

TL;DR:

The moments when your tween chooses something that makes no sense aren't moral failures or character flaws. They're a predictable feature of a brain mid-development — and understanding that changes where your influence actually is.

He Knew. And He Did It Anyway.

You heard about it three days later.

He'd told you he didn't want to. His friends kept pushing. And somewhere in that space between knowing and deciding, something shifted — and he went along with something he knew, on some level, wasn't right.

When you asked him why, he said I don't know. And the thing is — you believed him. That's what made it so hard.

This is one of the most quietly disorienting parts of parenting a tween: watching a child who clearly knows better make a choice that doesn't match what they know. It can feel like defiance. Or like something in their character you don't recognize. Or like all the conversations you've had just disappear the second you're not in the room.

None of those things are true. But what is true is worth understanding — because it changes everything about where your energy goes.

What's Actually Happening

Here's what child development research consistently tells us: in the tween years, the emotional brain and the reasoning brain develop on completely different timelines.

The emotional brain — the part that responds to social pressure, to the feeling of being left out, to the pull of what everyone else is doing — is essentially fully online by 10 or 11. The reasoning brain — the part that slows down, weighs consequences, and asks but is this actually what I want? — isn't fully developed until the mid-twenties.

So in a fast-moving social situation, your tween isn't ignoring what they know. They're experiencing a real competition between two parts of their brain — and in the moment, under pressure, with their friends watching, the emotional brain almost always wins.

This isn't an excuse. It's a target. Because the question isn't how to get them to know better. It's how to help them build the pause between the pressure and the choice.

Where Your Influence Actually Is

Most of the parent conversations about tween decisions happen in one of two places: before (here's why that's a bad idea) or after (what were you thinking?). Both have their place. But neither is where decision-making capacity actually builds.

It builds in the small, low-stakes moments. The everyday choices that don't feel like a lesson.

Try this the next time your tween is weighing something ordinary — a minor plan with friends, what to do when they're bored, how to respond to a text: "What's your gut saying?"

Not what's the right answer. Not what should you do. Just: what does your gut say?

What you're doing is training them to notice their own internal signal — the quiet voice that exists before the social pressure floods in. That voice is the foundation of every genuinely good decision. And it gets stronger the more it's asked for.

Bloomster's Making Responsible Choices course works through this directly with tweens — building the specific skill of identifying their own reasoning before the pressure of the moment takes over.

Try This Before Next Monday

The next time a decision comes up — big or small — don't lead with the answer. Lead with the question:

"Before you decide — what do you actually think?"

Then wait. Let them find their own thought before yours arrives. You're not withholding guidance. You're practicing something more important: teaching them to hear themselves first.

The decisions that confuse you aren't random. And the influence you have is more specific — and more powerful — than you might realize. 💛
