Expectant moms get a lot of advice from the Internet, friends, and even strangers. It's a lot of judgment, given that this miracle of birth has already happened 13 billion times without anyone telling mothers to eat purple vegetables or their child won't get into Stanford.
The digital age, where publication is cheap, coupled with epidemiology which can show almost anything, has led to a lot of confusion. But when the word "stillbirth" is invoked, as was recently down in The Journal of Physiology, pregnant women will panic.
Yet they shouldn't. No babies were harmed in a study which nonetheless claims babies could be harmed if moms sleep on their backs.
