Stuff like this terrifies me

I know stuff like this is what is going to keep me up at nights as a parent ... Well that and the thought of Sarah Palin as president in 2012 (ha!).

But I have always been "that guy" and would worry about stuff like a little kid under my watch falling through a seemingly good railing. I remember when I was maybe 9 or 10, my family took a vacation to Niagara falls. My sister for whatever reason INSISTED on leaning over the railings and I remember literally walk behind her and holding her shirt to make sure she didn't fall. Now that I am going to have a kid I don't know how I'm not going to develop an ulcer ... I might just wrap him in bubble wrap and attach a leash.
