Austin's Trail-a-bike finally came in and it was worth the wait. I think it will be great therapy for him with balance, stretching, and strengthening. And best of all he loved it! Tommy I think was the most happy for him which was really nice because sometimes they just don't get along the best. I'm thankful that we got that nice seat back that gave him more support because there's no way he could have stayed on a regular seat. However I think he will be able to eventually. In fact the improvement from him in just 2 days has been nothing short of remarkable. He was so wobbly and couldn't barely get his feet on the pedals to yesterday he was sitting much more stable and was even able to get his pedals around occasionally. He'll only get better.
Here is a short video of his first ride around the driveway.
