His fearlessness showed through at the parks we visited yesterday as well. There was the time he was going to just go off a 4-foot drop that was at the top of the rock climbing wall. He didn't try to walk off it. No, he safely sat down on his butt and was going to scooch off it. Safely, of course. (I caught him.) Then there was the time he thought it would be a good idea to walk across the uneven steps that were suspended 3 feet off the ground, with each step about 1 foot apart. After catching him multiple times, I lowered him to the ground.
As much as he does need to develop a healthy appreciation for his own safety, his fearlessness gives him the freedom to try new things and continue to push to do more to keep up with AJ and the other kids. He walked, safely and successfully, up and down many gradual ramps at the park all by himself without holding onto anything. He walked up a steeper ramp with rock climbing holds while holding onto the rails, all by himself. He continued to pop up to his feet whenever he fell (or dropped to his butt to safely navigate an obstacle that he knew he couldn't manage on his feet).
That fearlessness gives him freedom ... and lots of scrapes, bumps and bruises. (Most of which he doesn't even notice, so I suppose that further enables his fearlessness.)
