Not I, but my mum and my SIL. I wasn't even born for my mum's loss, but I was with my SIL during her loss. Her baby was full term, and one night quit moving. She called the doc freaked out that she wasn't feeling movement, but was told it's common (and it is) at this late stage because of there being so little room to move. The next day she went in, and no heartbeat.
The entire experience was awful. Of course, the hospital did their best, but from the black tag on the door (so no one would go in all excited and say the wrong thing), to 10 hours of labor... it was a devastating process. Come to find the cord had wrapped so tightly around her little girl's neck that her completely heathy baby had suffocated. No bloodflow or O2 to the brain at all. Even by the time my SIL had noticed no movement, it would have been too late... because it only takes a few minutes... and of course, no one notices just a few minutes of stillness. That happens all the time.
The hospital *always* does an exit counsel with social workers after a still birth, but my SIL & BIL were in too much shock to really take in what was being said during the exit counsel. If one of my other BILs and I hadn't both worked in hospitals and known the "drill" neither my SIL or BIL would have known that they were invited to take part in individual & group grief counseling free of charge, or that there were support groups out there to help the parents and families of stillborn children. So they were counsel free for several weeks, and both in quite deep depression, as were both sets of their own parents (from both losing a grand baby and fear/sadness for their children. My SIL's mother actually made the entire process much much worse because she would vacillate between yelling at her daughter to "get over it", and blaming her or her husband, just generally being a giant pain while my BILs father actually quit eating more than enough to keep a bird alive for several months and lost over 50lbs being stoic in his own grief). When my BIL and I started asking them why they weren't taking the hospital up on their grief counseling, we realized what had happened (their being shock) and got them in.
So if you aren't in counseling I strongly urge you to do so.
My mum has lost 2 children. One at birth, and one later in life. She says that of the 3 (miscarried and actual children), her stillborn child was the hardest, because she had so many hopes and dreams, and so many unaswered questions for the child she never got to know. She didn't know if he was fussy, easy, adventurous, like trucks or dance or both...etc. She says that she spent over a year with nothing but unaswered questions swirling around in her mind, and that the loss is why she took up running marathons. So that she'd have an excuse to just THINK about her lost baby without anyone bugging her/ telling her to stop. That she could run and run and run, and no one would pester her or guilt her.
My heartfelt condolences.
