The "happy ending" where one of the parents and their three other kids find out that the other parent likely killed the older brother they never met? That doesn't sound very happy to me, but maybe we have different definitions of happy?

When I tried reading into the causes of so-called SIDS it seemed like at least some of the cases were a catch-all diagnosis that included cases where parents inadvertently killed their infants (eg co-sleeping and rolling onto them). Fundamentally I think there often isn't much upside to fully fleshing out the truth of cases where parents have already paid the heaviest price.

Man, SIDS. It's specifically non-specific, but the worry it causes is quite specific.

My daughter, as a baby, always managed to find a way to sleep on her stomach. Wouldn't sleep on her back, but almost magically by comparison would fall asleep lying on her stomach (face to one side or the other, not straight down, obviously - I hope). We tried various combinations of devices, arrangements of pillows and cushions, tight wraps, to keep her lying on her back, but babies are remarkably, if involuntarily, wilful (or she was, anyway, and remains to this day).

I worry about very few things, but for the first few nights we'd regularly get up to check on her, and literally be holding our breath waiting for her to expel hers.

Out of necessity the every-parents-SIDS-fear, from allowing the baby to sleep on their stomach, had to be removed from our psyche so that we could continue to function day-to-day.

Said baby is now, thankfully, a semi-healthily functional teenager. As functional as teenagers get anyway :)

While "happy" isn't the word I'd use, that seems better than knowing that this could happen to any baby at any time and nothing would be done.

We don't know it was the parents. Could've been a babysitter. Could've been a grandparent. New parents often have help.
