Mercury is toxic to the nervous system of the developing fetus.

The fetus, newborns and children are especially susceptible to mercury exposure because of the sensitivity of the developing nervous system. Women of childbearing age and children should avoid eating large predatory, non-fatty fish (such as shark) that can have high levels of mercury. Children can also be exposed to mercury from some herbal medicines and some teething powders.
