Research shows pregnant woman's stress harms fetus

Via The Guardian (UK):

Stress experienced by a woman during pregnancy may affect her unborn baby as early as 17 weeks after conception, with potentially harmful effects on brain and development, according to new research. The study is the first to show that unborn babies are exposed to their mother's stress hormones at such an early stage in pregnancy.

The findings, published in the journal Clinical Endocrinology, come after separate research on animals showed that high levels of stress in a mother during pregnancy could affect brain function and behaviour in her offspring, and other evidence suggesting that maternal stress in humans can affect the developing child, including lowering its IQ.
