Look ma' No wheels!

Isaac is only 3 years old and to me, this seems a bit crazy. About a month and a half ago one of his training wheels broke, so his bike had been sitting in the garage. He loves his bike and wanted it fixed so, I took off both training wheels and tried to encourage Isaac to sit on the bike and try to ride without them on, but he would have nothing to do with it.
About two or three weeks ago, Isaac was outside playing and decided to try his bike. He just sat on it at first and would lift his feet and coast down the drive way, all of this unbeknown to me. I was inside working in the kitchen, like I always seem to be, and Isaac comes running in sort of in a panic. He says "Mom, come here you have to see this." So I hurry over thinking something serious has happened. I go outside and Isaac jumps on his bikes and shows me how he can ride. I was in shock! He didn't have any help, and he wasn't wearing his helmet.
This is the video below of him on his first day without the training wheels (there is no sound). After we shot this I made him get his helmet on.
