I'm not an expert on family court outside of DCYF involvement. But it's all about making the judge happy. Do anything the judge asks and don't complain. Offer to do things you're not required to do. Treat the judge like a potential employer but don't schmooze too much. Judges love therapy. Get a therapist and have them write a letter. Waitlists for therapy are long right now. Get on every waitlist for every therapist and document when you got on and follow up weekly (and document that, too.) Document EVERYTHING.

Letters from non professionals (as in anyone whos not a therapist or involved in the case-- relatives, employers, pastors) aren't given a lot of weight because they could just be crazy randos.

Demonstrate your insight and parenting skills. If you're not seeing your kid at all, don't talk about how much YOU want to see them; talk about how your kid must feel unloved or unwanted or lonely. Make it all about how you can make your kid's life better. Never, ever show anger.
