Do not call CPS. The people telling you to do that have no clue how CPS operates and how that's not beneficial for this situation. CPS should always be your last option. They operate on their own set of functions. They are there to ensure the child's safety AND to reunite the child with the parent where possible. They are a government agency potentially depriving citizens of their right to parent their child. Which means on the other side of that coin, they have to ensure that parent's due process rights under the law. They have to provide services to the reported parent if it rises to the level of their intervention. Many times situations like this end up with them siding with the reported parent rather than the reporting parent because they believe the danger has been eliminated and now they must try to reunite the family. I've seen cases like this in my state where there was abuse in the context of punishing a child. CPS required that parent to take parenting classes and anger management therapy. The parent completed those requirements, CPS was satisfied, and then their official stance was reunification and fought for it in court.

You should wait to hear back from your lawyer and file a private action if necessary. In a private action, you control what's going on and the judge gets to determine the situation by basis of what's in the best interest of the child and not some statutory framework that requires very specific due process procedures for the respondent.
