Like this place:
That kid can fall off his bike all he wants; he won't get hurt.
But we live in Harlem, and we must adjust. One year ago, the little goober decided he was ready to try riding without training wheels, so we woke up early and went to the playground before the ball players and other kids arrived. I reminded him that it would be okay to fall and that we would just try as many times as we needed to get it right.
He was ready.
I held his seat, he started pedaling, he took off, I was proud.
It wasn't the ideal place to teach him, but when are we ever in the ideal place to teach our kids?
