There's no way to prevent Down syndrome. However, if you're at high risk of having a child with Down syndrome or you already have one child with Down syndrome, you may wish to consult a genetic counselor before becoming pregnant.

A genetic counselor can help you understand your chances of having a child with Down syndrome. He or she can also explain the prenatal tests that are available and help you figure out the pros and cons of testing.
