Okay, in an attempt to get the true facts as they are known out here, I am going to list information from the National Down Syndrome Society's web page on the causes of Down syndrome. These are the people that know guys, not some misinformed doctor telling a mom she caused Ds with poor prenatal care, or someone talking about "research" that is so secret she can not reveal its source. If you think for a minute that there are not doctors out there who are misinformed about Down syndrome....I am here to tell you that any mom I know (and I am one) of a child with Ds knows more about the issue than their own OBGYN or pediatrician. The only doctors I see that know more than I about my son's conditions are the developmental pediatrician. Here is the info from the site;

"Nondisjunction

Nondisjunction is a faulty cell division which results in an embryo with three number 21 chromosomes instead of two. Prior to, or at, conception, a pair of number 21 chromosomes, in either the sperm or the egg, fail to separate. As the embryo develops, the extra chromosome is replicated in every cell of the body. This faulty cell division is responsible for 95 percent of all cases of Down syndrome.

Why nondisjunction occurs is currently unknown, although it does seem to be related to advancing maternal age. Many people are surprised to find out that 80 percent of children born with Down syndrome are born to women under 35 years of age. This is because younger women have higher fertility rates. It does not contradict the fact that the incidence of births of children with Down syndrome increases with the age of the mother.

Although nondisjunction can be of paternal origin, this occurs less frequently. Because this error in cell division is often present in the egg prior to conception, and women are born with their complete store of eggs, it has been postulated that some environmental factors may be implicated in nondisjunction. However, despite years of research, the cause (or causes) of nondisjunction, is still unknown. There seems to be no connection between any type of Down syndrome and parents' activities before or during pregnancy."

You will notice....the quote...seems to be NO connection between any type of Ds and parents' activities before or during pregnancy. Please, families of children with Ds have to put up with an awful lot of ignorance and misinformation when it comes to understanding our precious children. Do not speak of what you don't know. Point people to informational sources that are legitimate. The above info is found at www.ndss.org
