Get some prominent people to write letters of support for you, Doctors are really good(including people with a doctorate), Pastors (or if your desperate priests) or anyone else who has social capital in the court system.
Mail copies of those letters to anyone involved in the case right away.
This is very powerful in our legal system.
I know the judge. My fear is that if CPS grabs those kids, it's out of his hands. Once they go into the pipeline, that's it.
Letters from other people will still help.
