Jacob can now ride his bike without training wheels. He is so proud of himself. We have a little 12-inch bike that was Cody's. When Cody learned to ride without the training wheels, the training wheels accidently got thrown away. I went and bought new ones, so Jacob could use the bike, but they never stayed tight. Jacob would ride for a little bit, and then they would come loose, and Jacob would freak out, and not want to ride the bike anymore. After about a year of this, I finally just decided to take the training wheels off, and teach him how to ride. Of course, since he is so tall, he is now too big for the 12-inch bike, but I figured it was better to learn on a little bike....less distance to fall. ;) He was a pro in about an hour. He is now ready for a bigger bike, but since Cody is so short, they need the same size...that means I have to buy another bike. Or just let Jacob ride the teeny one until he grows into the 20" ones that we already have. :)
