Is this a log you keep for yourself or send back and forth with the parents? I don't do logbooks currently, but I do send a nightly email to parents and extra emails for anything like an injury. This incident was so insignificant that I did not even mention it to the parents...I am not even sure if that is how he got bruised. Do you log every small incident that takes place? I will do what I have to do to protect myself, but just trying to see what makes the most sense.
