I'm a single father who has shared custody of my 7 old son with his mother. I received a call from a social worker on Tuesday informing me that there has been a claim of excessive physical abuse on my part. Now, beyond the occasional wrestling with my son, or light hearted "You're being a doofball" tap to the back of the head (to which he responds with punching me in the nuts) there is zero physical interactions beyond hugging him.

Now, I know for a fact that it was his teacher that made the claim, as the call was made to a cell phone that few people beyond my friends have the number to.

I'm freaking out pretty badly and don't know what to do. Any advice? I'm in Canada, if that helps.
