The environment can have an important influence on development, and this also includes the prenatal period. The growth that happens during the nine months of prenatal development is nothing short of astonishing, but this period is also a time of great vulnerability. Fortunately, the effects of many of these hazards can be greatly lessened or even avoided entirely. While dangers do exist, the vast majority of babies are born healthy.


Today, researchers understand a great deal about teratogens, a term used to describe the broad range of conditions and substances that can increase the risk of prenatal problems and abnormalities. Teratogens can cause a wide range of problems from low birth-weight to brain damage to missing limbs. In order to minimize and avoid these dangers, it is essential to understand what poses a risk to the fetus and how such dangers can affect development.
