Why tantrums happen, and what actually helps

A tantrum isn't bad behaviour or a discipline problem. It's a two-year-old brain feeling more than it can yet manage and what you do in those four minutes matters more than anything you say afterwards.

By around eighteen months your child has enormous feelings, strong opinions and almost no ability to regulate either. The part of the brain that manages impulse and recovery is still years from being built. So when the wrong cup appears, or a shoe goes on the wrong foot, the feeling arrives at full volume with no brakes attached.

This is developmentally normal. It peaks between two and three, and it passes. What helps in the meantime is not a clever phrase; it's your steadiness.

What’s happening in your child’s brain

In the middle of a tantrum, your child has lost access to the thinking part of their brain. They can't hear reason, negotiate, or remember the rule you agreed on this morning, not because they're refusing to, but because the wiring for it is temporarily offline.

This is why explaining doesn't work mid-storm, and why "use your words" lands as noise. Your calm nervous system is what brings theirs back down — a process called co-regulation.
