Thursday (or was it Friday?) I backed over Pauly's bike. He's not even supposed to have the bike in that part of the driveway at all, so I don't feel too guilty. Besides, he's had the bike for almost 3 years, and it was just about too small for him last summer and is now way too small. The only damage was to the training wheels, which were both smashed.
Saturday Pauly suggested that we just take the training wheels off, so he could learn to ride it without. And he just jumped on it and started riding it. Bob helped steady it so he could take off twice, and then he could start and stop himself. He's been riding all over now. That was easy for us, and quick! Hopefully we'll be able to get a bike that fits him sometime this summer.
