To elaborate on what Clysta Said.  Trisomy 21 which is Down Syndrome isn't normally fatal and DS children can lead very full lives.  Trisomy 18 which is Edwards Syndrom on the other hand is fatal. Most babies don't make it to birth, those who do only live a few hours and RARELY a baby with edwards syndrome can live up to a year.

LosingMyMindInGA is right.... but to elaborate on some of it....

T13 and T18 are fatal. I believe that only %1 of T18 pregnanies make it to birth and %1 of those live to 1 year.... most are on some form of life support

T21 isn't normally deadly when babies are carried to term but there is actually a fairly high mortality rate during pregnancies due to severe heart defects or other physical defects (that can be detected before the decision to terminate is made).

My firstborn TJ has Down Syndrome or Trisome 21

It's a genetic disorder in which you have 3 copies of a certain chromosome instead of the normal 2. There are a couple of common ones in humans, such as Trisomy 21, 18. (DS and Edwards syndrome) You can also get it of the sex chromosome as well so it would be like XXX instead of XX.
