answer:I would talk to my parents and ask them what happened. For something like this to happen after the history I have with my parents, it would be really unusual, so I would be concerned that something was wrong with them or that something happened out of the ordinary during the visit. Once I knew and understood what happened and why it happened, I would make a decision based on that information as to whether they would ever watch my child alone again. My mom watched my son a lot when I was in nursing school, so I know she is capable of doing so. If he came back in a state of neglect, it would mean that something was wrong with my mom (possibly something medical or emotional).
