Sarah riding her bike with no training wheels

I can't believe that Sarah is old enough to ride a 2 wheeler with no training wheels. Saturday morning Russ took Sarah outside and took of the training wheels off her bike. She was very excited but also a little scared. When they began to ride, she would scream all the while pedaling. She got very good at pedaling, but isn't so good at stopping. She did learn to jump off. We only had one scraped knee and one small dent in the neighbor's car. They were very OK with the small dent. It can be buffed out. She has wanted to go ut every day since to ride her bike.
