I can't get DH to wear his helmet. I get so mad when I think about it. He keeps telling me "i'm fine! I know how to ride a bike!" Duh! It's not him I'm worried about so much as the idiots texting-and-driving.

I've ingrained helmet-wearing into my DD. She won't go near her bike without her helmet. Of course, I'm sure that will change as she gets to be a tween or teenager.

Get a neurosurgeon, ER doc or other medical professional to talk to him. Seriously. Either that or take out a million dollar life insurance/disability policy and if he complains about the cost, tell him tough. Pretty soon you'll have "how come Daddy doesn't?" conversation with your kid.
