Behavior Following Visitation

[TXDad]

Does anyone know where I can find articles/information pertaining to young children acting out following visitation with a NCP?  The CP is attempting to use our son's acting out as a way to limit visitation but I believe that is simply because he was upset at having to say bye to me (I live in another state) and that this is fairly normal.  I have found various posts on the internet but was looking for something that would stand a chance of holding up in court.
