  1. One a size big to grow into
  2. One that fits right now ✔
  3. A grown-up's helmet with extra pads

Why: A helmet that is too big can slide around and won't protect well. NHTSA says to buy one that fits now, not one to grow into, and readjust it as needed.

Huh, didn't know that: Kids are more likely to wear a helmet they think looks cool, so let them help pick it.

The dad joke
I bought my helmet a size too big. Now it's a head of its time.
