Where can I buy tiny helmets?

No, seriously. I want one. Or two. I never considered myself a paranoid parent. I like to think of myself as laid back and relaxed - I mean, I make sure my kid naps and I'll try to keep sharp and poisonous items out of his way, but I'm not one of these mom's with the energy to sterilize everything, to lock all cabinets with childproof gadgets, or to freak out when he gets a hold of a paper clip.

And yet I would seriously consider forcing my child to wear a helmet 24 hours a day.

I mean, he falls that much. He's always bumping his head.

And tonight he fell - he was running and just fell, didn't trip, just FELL... and usually he gets up and says "ouch!" to let us know he fell. He sometimes cries that fake "heh, heh, heh" cry so that we'll pick him up to comfort him. But this time he let out a real scream. He was so upset. And Steve got to him and picked him up but he was still crying...

Best as we can figure out he fell on his face - FLAT on his face. For a few minutes, a few terrible and horrible minutes, we actually thought he broke his nose. I thought my 18 month old baby had broken his nose. It was awful. I was very close to just throwing him in his carseat and driving us all to the emergency room. Without turning off the stove, putting on my shoes, or otherwise preparing myself for the cold.

It only lasted a few minutes, though. There was no blood that we could see. Nick wasn't interested in milk, but he laughed a little bit when Steve put him on his shoulders. In five minutes he was playing with his toys, back to normal. My blood pressure, however, was just starting to come down.

I know kids get hurt, and that this is part of development and life and that I can't keep him from every little thing, but the thought of something like that happening to my kid...

So again, if you know where I can get baby helmets, ones with face guards...
