Why shouldn pregnant women sleep on their backs?
It may be recommended for pregnant women to sleep on their left side, but, it’s not necessary… It depends on how the woman feels; if it’s comfortable for her… With my first 3, sleeping on my left side was the only way (for me), but with this last one (I’m 7 months), sleeping on my back is most comfortable… I get downright short-of-breath, if I lay on either side!
