How much beating can a little (well big in his case) head take? I'm worried he'll crack open one day. I'm talking about falling backwards or bumping his head on things. I think I need to find a helmet for him.

I know, it is scary. My babies have always been in that crawling and walking stage in a 2 or 3 level house, so they've each taken a small tumble down a couple of stairs or fallen off of a chair or done something else that pretty much made my heart beat out of my chest. It's scary!

That was one of the most worrisome things for me too. It's scary, but just know that kids are like Tonka toys...built tough. :lol
