DS6 just learned. He was overusing his training wheels, and I said "that's enough". I encouraged the mess out of it b/c he's the "I can't" perfectionist if he thinks it's too hard. At first we tried to hold on while he was going, but that proved to be a disaster. So, I got on my bike and showed him how to balance and take off and brake. And bam, he just did it. Now if I can get him to STOP before he gets in the garage and crashes into everything!
