Down Syndrome is a genetic defect. There is no proof as to what causes it, only that older (usually 40+) women are more likely to have a Down Syndrome baby. I have a 9 year old son with DS, and although life is more challenging, I couldn't imagine not having him around. He knows his Daddy loves him and in the end, isn't that what being a parent is? E-mail me if you need more information.
