Also awesome when your little ones figure things out too! My son, who is almost 13 now, rode in front of me on his first bike. I just noticed his training wheels weren't even touching, so I just took them off. Has never stopped since!
I always rode without helmets and did stupid things as a kid. Used to go play war with real BB guns when we were kids. Shoot each other in the shoulder or arse! Great fun. Not recommended, but great fun!!
"he told me that he wanted to practice more and for me to leave him alone" -- that's what I'm talkin about! I'm proud of him, too! He's a fine young man.
