I’m in Adelaide, Australia.

My ex and I have each had an individual session with a psychologist/parenting professional. Tomorrow we have our first joint session together. From what I understand, this is before mediation or court, and the goal is to try to sort out parenting arrangements.

She is reputable here, but I have no idea what to expect.

I’m worried my ex will make claims about how I treated her or try to paint me badly, instead of focusing on the kids and practical parenting.

Has anyone been through something similar?
What usually happens in these joint sessions?
Any tips on how to handle myself, what to say, what not to say, and how to stay calm if things get emotional?

Any advice is appreciated.
