Ten days ago our oldest turned a decade! I enjoy having his birthday be during the Christmas season for many reasons--but it does make things rather hectic. I don't ever want to him to think his birthday is an after thought and thankfully he is very easy going as to how we celebrate.
It's pretty fun to watch. I haven't driven it yet--it goes 30 mph so when it crashes it has the potential to be really damaged. We've already made two trips to the hobby shop for replacement parts.
