Experience with Bipolar Moms?

I have a Labor Doula client who is bipolar and having a hospital birth for the first time. She and her husband are amazing people and I feel so honored to be working with them.

I'm wondering if anyone has any experience working with a bipolar mom during labor and postpartum that they would like to share with me. Anything you share that is confidential will not be published on this site. If you know of any good resources I can access about how hormones affect bipolarity, things I should be aware of, etc would be awesome.

Thanks so much.
