I have been in a similar situation in the past and now have three healthy children. There isn't an easy answer to this other than to take the best medical advice you can (recognising that the medical aspects are only part of the equation), be prepared for the long haul, persevere, treat setbacks as an inherent part of the journey, and be reassured that if you do have the mental resilience to keep going, you WILL have healthy children. Happy to talk further if it helps.

Down synndrome often occurs when?
The Occurrence of Down Syndrome Most of the time, the occurrence of Down syndrome is due to a random event that occurred during formation of the reproductive cells, the ovum or sperm. As far as we know, Down syndrome is not attributable to any behavioral activity of the parents or environmental factors. The probability that another child with Down syndrome will be born in a subsequent pregnancy is about 1 percent, regardless of maternal age. For parents of a child with Down syndrome due to translocation trisomy 21, there may be an increased likelihood of Down syndrome in future pregnancies. This is because one of the two parents may be a balanced carrier of the translocation. The translocation occurs when a piece of chromosome 21 becomes attached to another chromosome, often number 14, during cell division. If the resulting sperm or ovum receives a chromosome 14 (or another chromosome), with a piece of chromosome 21 attached and retains the chromosome 21 that lost a section due to translocation, then the reproductive cells contain the normal or balanced amount of chromosome 21. While there will be no Down syndrome associated characteristics exhibited, the individual who develops from this fertilized egg will be a carrier of Down syndrome. Genetic counseling can be sought to find the origin of the translocation. However, it is important to realize that not all parents of individuals with translocation trisomy 21 are themselves balanced carriers. In such situations, there is no increased risk for Down syndrome in future pregnancies. Researchers have extensively studied the defects in chromosome 21 that cause Down syndrome. In 88% of cases, the extra copy of chromosome 21 is derived from the mother. In 8% of the cases, the father provided the extra copy of chromosome 21. In the remaining 2% of the cases, Down syndrome is due to mitotic errors, an error in cell division which occurs after fertilization when the sperm and ovum are joined. The incidence of Down syndrome rises with increasing maternal age. From: Ali Sabah Al-Takmachi, College: Medicine , UOS Reference: http://www.nichd.nih.gov/publications/pubs/downsyndrome.cfm

What causes the abnormality in chromosome numbers in people with down syndrome?
It is most commonly caused by increased maternal age.Add: It is the result of nondisjunction of the 21st chromosome pair, in which the pair fails to separate, so that one cell gets an extra copy of chromosome 21.
Is maternal feeling a symptom of pregnancy?

Is blonde hair recessive or dominant?
Recessive gene of X chromosome. more common in men as they have only one x chromosome but in female there are 2 X chromosome. If one of X chromosome in female has this recessive gene, they become a carrier. If both the X chromosome in female has this gene, they show baldness
What are pair of similar chromosomes called?
HomologousWe receive one complete set of chromosomes from each parent. This means that for each chromosome, say chromosome 7, there are two copies in every cell of our bodies: the maternal and paternal copies of chromosome 7.The two copies of one chromosome are called a pair of homologous chromosomes.
