Suggestions for supporting the mom of a stillborn

My cousin went in for her 32 week check-up and found out that her son’s heart had stopped. She went that evening to deliver him. Like any mother, she has taken the loss very hard. This was her 5th boy. He was an oops baby but very much loved and waited for. The doctor has put her on Zoloft to help her depression. There isn’t anyone who has experienced what she has in our family and I would like to offer whatever support I can. I know support from others helped me through my miscarriage last year. I want to help her but my experience with child loss is different than hers. I was wondering if any of you had suggestions for how our family can help her grieve. We obviously don’t want to rush her through this because she needs to take her own time with it, but if any of you have ideas of how we may better offer our support then I welcome them. Thank you in advance.
