Apparently, older eggs and older sperm have a greater chance of having an extra copy of chromosome 21. A 30-year old woman is slightly more likely to conceive a DS fetus than a 20 year old, and by the time a woman is 40 years old, she has a 1 in 40 chance of conceiving a DS fetus. (1 in 12 by age 45). Down Syndrome means that someone has 3 copies of chromosome 21 instead of the usual 2 copies, and there's nothing you can do to prevent it or to cause it. It's a genetic fluke. It's also true that more DS babies are born to younger moms than to older moms. The main reason is that older moms (35 and up) are encouraged to undergo an amniocentesis between 14 and 18 weeks of pregnancy, because they are more likely to conceive a baby with a genetic defect. Young moms typically do not have an amnio, unless the doctor has another reason to suspect a problem with the pregnancy. The amnio gives a chromosomal analysis that can tell the prospective parents for certain whether or not there is DS or another chromosomal abnormality present. About 90% of all pregnancies with chromosomal abnormalities are terminated. Because older moms are more likely to know that the fetus has DS, and because most DS pregnancies are terminated, older moms are less likely to actually give birth to babies with DS than younger moms. Many younger moms with DS babies don't know that the baby has DS until he/she is born. And - there are many, many more younger moms than older moms. Does that make sense?

The CHANCE an older women has a child with Down's may increase but that does not mean that all children born to older women develop it. Down's Syndrome is a genetic anomaly that does not have a specific cause. It occurs equally in human births, around the globe. Around 1 in 800-1000 births are a Down's baby. 80% of all children born with Down’s are born to mothers under the age of thirty.

My mother and i had a chat about this topic awhile ago (she lived during the era when birth control pills were first introduced) downe syndrome and autism have increased since the introduction of birth control pills on the market. If for whatever reason the mother got pregnant while taking birth control pills...i believe (and this speculation) that her chances of conceiving a down syndrome child is increased. Ask the mother to see if see was on the pill or depo. one theory i have…is birth control.
