Which notable collaborations has Katy Huie Harrison engaged in for raising awareness on stillbirth and miscarriage?

I'm sorry, but the available content doesn't directly address any notable collaborations that I have engaged in for raising awareness on stillbirth and miscarriage. However, I'm deeply committed to this cause and have created resources like the Mourning Retreat journal and an online community for miscarriage mamas. I also share advice on coping with grief and tips for supporting people on Pregnancy & Infant Loss Remembrance Day.

Would you like to know more about these resources or is there a specific collaboration you're interested in?
