Check out the Chicago chapter's website. You can also join their Facebook page and Instagram page.
The Star Legacy Chicago Chapter Local Resource Guide has some really incredible resources that I recommend checking out.
This group is for moms (or birthing people) only. It is a 6 week program that is facilitated by mental health professionals for a small group of moms. The group used to be in person in Evanston, IL, but is currently virtual. Call 847.864.7957 or email at info@beyondthebabyblues.org to sign up. You can also check out their website.
I made a Facebook group for loss parents in Chicagoland. I post new resources when I find them and in person events. I'm hoping that it will become a place where local loss parents can connect. Consider joining if you are in the Chicagoland area. Chicagoland Loss Parents Facebook Page
