This may sound weird, but yesterday when I got home from work Jen and Avi were outside playing with the neighborhood kids. I noticed that Avi just took off on her tricycle, pedaling all over the place with no problems. This is the first time she has really been able to sustain the pedaling motion for more than a few seconds. And when she started she couldn't stop - she pedaled for about 30 minutes just chasing the older girls on their bikes. So, I guess she finally "got" it and knows how to ride her bike now - this was very cool.
