Yup, just document word for word and keep it on file. Sounds like it could have been anything. It could have been a dream! Who knows. Kids are funny, and without visible marks I wouldn't worry about it. He may have seen something on TV. I wouldn't even mention it to mom.

We have to remember, it's not our job to teach parents how to parent.

I wouldn't get involved in this one. Sounds pretty minor. But really praise this little guy for telling you and make sure he feels safe to tel lyou anything. Fact of the matte ris... if he told you, he'll probably say it to someone else too.
