The second message was, IIRC, motivated by a statistic showing several cases of parents inadvertently smothering their infant children when rolling onto them while asleep.

Now I have no idea if the number of cases was statistically meaningful enough to warrant action, compared to other public health risks. But I can sort of see why someone would be motivated to "do something", considering how devastating something like that must be, even compared to other accidental deaths of infants.
