You can thank the Child Support Standards Act and its follow on legislation (the Bradley Amendment among others) for your plight.
Parental alienation is considered "junk science" by appellate division certified psychologists because they engage in parental alienation as a function of their jobs. They have to split a family in order for child support to commence so that the state can get federal child support enforcement funds.
This means the judge will not react to allegations of parental alienation because his orders are reviewed by the appellate division.
What you need is an overall case strategy that cannot be described in a few paragraphs. Your case file has to be reviewed in detail. A plan has to be created to address the focus of the conduct of the father. Then, procedurally, the case has to be carefully executed to have a chance at fixing the problem.
You need a local lawyer who is versed in expert witness management and cross examination. I may also recommend a trial consultant versed in areas of psychology that concern children and families, the delivery of mental health services, testing, evaluations and local family law.
