Leif very soon got the hang of the climbing wall and accomplished it on his own repeatedly after that.
For me, up inside the *Structure*, (as the kids have always called it) made a great perch from which to capture the expressions of a budding climber. Effort, worry, pride, concentration. He's only 2 1/2 of course but strong.
Leif's two big brothers will not be able to mess with him without consequence for much longer.
Extreme sports will probably come into his future whether his mother wills it or not. With three fearless, energetic boys, I believe she is already steeling herself :).
