What to call a nonbinary parent?

I'm curious, what term should we use to address a nonbinary parent? I've heard of using "they/them" pronouns, but I'm wondering if there's a specific term or phrase that's widely accepted and respectful within the LGBTQ+ community. It's important to me to ensure that I'm being inclusive and considerate in my language, especially when discussing such personal topics. Could you provide some guidance on this matter?
