Learning to ride without training wheels

We took the training wheels off of Dane's bike the other day.

"Don't let go Dad! Are you holding on"?

He's got it! Unfortunately he eventually fell and hurt his elbow pretty bad and wanted to know how long his training wheels had to stay off. We have been practicing everyday and he's more confident now. No training wheels...he starts kindergarten in the fall...he gets dressed by himself...and if you ask him he'll tell you he knows everything about everything now and can do everything by himself because he is five years old...where did my baby boy go?
