James is well on his way to appreciating the concepts of friction and centrifugal force as it relates to going around corners quickly. I'm sure he'll be fine.
Eventually, we'll make a pilot of him.
I've noticed toddlers wearing foam head protectors, like boxers or hockey players, but we just live with the bruises. Tripped over his feet, as near as I could tell. Usually they do this a day or two before you have an appointment for pictures!
My second son was (is?) so full-steam-ahead that, when he's finally old enough that I'll let him on here, I'm going to have him sign on as "NicknamedCrash". He's had stitches on his head five times and medical-grade Krazy Glue twice.
