Ressources for parents of children with DID ?

Hi guys !

I was searching things for my mom, to help her understand DID better, and maybe how to approach it better as a mother, but I realized I wasn't able to find anything beside the SIDRAN resources, which seems to be mainly for parents with young children with PTSD.

My mom aside, it surprises me a bit. I mean, of course DID often happen because of parents, but not both parents had to be actively abusive, and sometimes none of them were ; and they might want to help, while not knowing how as most of the resources are designed for friends and partners, not parents.

I was wondering if you, guys, know about resources for parents with teens or adults with DID ?
