Researchers are looking for women who are currently pregnant or think they may get pregnant in the next few years for a nationwide health study.
The National Children's Study will follow some 100,000 kids from birth to the age of 21 in what is said to be the largest long-term children's health study of its kind.
They hope to learn how the environment influences children's health, development and quality of life.
