Future X Games Stars?

So today we took Max, Henry, and Mick to the BMX Park in Pleasanton. Keep in mind that Max has only been riding a bike for a few weeks. His friend Mick, by contrast, is an "old pro" at this point, having mastered the two-wheeler over a year ago at the ripe old age of three. I wasn't sure if Max would enjoy the park or become easily frustrated and ask to leave. I figured Henry would have fun puttering around in the dirt on his balance bike. As it turns out, all three boys had a blast! Henry was all over the place on that balance bike, earning stares and nods of appreciation from teenage daredevils. Max was absolutely fearless and he took a couple hills that almost threw me into cardiac arrest. I wasn't sure if I should feel proud of him for his skill and his nerve or if I should castigate myself for being the most irresponsible parent in the world (what kind of mother takes her not-quite-four-year-old son to a place where he can hurl himself down huge hills at great speed on top of a vehicle that he has only just learned to ride???!!!). The answer, of course, is that I felt both proud and terrified at the same time. Kind of sums up parenting, doesn't it?
