I am 24 and 3 yrs ago I had a stillborn ( found out on my exact due date as well). So, I have a few suggestions for you. One thing you could do is be a good listener (goes without saying ) , never make comments like " it happened for a reason" "you can always have another one" . That just made me feel bad, like there was a silver lining to what happened. Maybe when you visit her at some point you could see pics of the baby (if she had any taken ) . Even though that might be very hard for you to look at. I had pics of my baby boy and they brought me to tears of course , and his appearance was difficult to look at, but I still liked it when family and friends wanted to see the pics. It made me feel like even though he had passed over he wasn't gone. And he was still important to the family. Another thing I did was attend a support group at the hospital, maybe suggest that to her. Maybe give her a book on grief and stillbirth. That helped me a little. Send her "thinking of you" cards since your far away. On the anniversary, send a card. ( I wish my family did this) on special holidays , like christmas you could send an engraved ornament or make one with the babies name on it. Every year to come , she'll be thinking of her little baby, so it would be nice if you remembered him too on special days. I know she would really appreciate that. If she got the baby cremated(we did) I got a special heart necklace ordered from the mortuary , where they enclose some of the ashes inside the heart. I never take off mine. Eventually I went on zoloft for about a yr. Which helped me tremendously. Really though , there is nothing anyone can do to take her grief away. I still think about my baby every day, even though I had another baby and I have a supportive family. It still was the worst experience of my life. Luckily , for me time did heal somewhat. So hopefully things will get better for your sister too. I know I rattled off a lot there, but I sort of wish my family would have got a message like this.
