6.35mm.
That’s about the width of a pencil.
And that’s all it takes.
A young child’s spine can stretch far more than that in a crash - like an elastic band under tension. But the spinal cord inside it can’t stretch the same way.
That tiny difference is where serious injury happens.
Evidence referenced by the National Library of Medicine highlights just how little stretch the spinal cord can tolerate before damage occurs.
And this is where direction matters.
Forward-facing allows the head to be thrown forward, stretching the spine and putting that delicate cord under strain.
Rear-facing works differently. It supports the head, neck and spine together, spreading the force and reducing that stretch.
Same crash.
Very different outcome.
It’s not about comfort.
It’s not about what they prefer.
It’s about protecting something you can’t see - but can’t afford to risk.
