I'm 35 and I had my first at 33, so I'll be interested to see what's different about how I'm treated having reached the threshhold. I definitely intend to decline the amnio they will recommend.

Interesting thing about twins. It is true that young moms (late teens and early 20s) and older moms (late 30s to early 40s) have a higher incidence of fraternal twins, because their bodies have a greater tendency to ovulate two eggs on any given cycle. It is also true that any woman will ovulate two eggs on some cycle in her lifetime, sometimes a few times, so therefore any woman has the possibility of having fraternal twins. Fraternal twins are said to "run" in a family if the women in that family have an inherited trait that causes them to ovulate multiple eggs on many cycles, thus making it more likely that a twin pregnancy will result.
As for identicals, scientists still have no clue why a fertilized egg will sometimes divide and create identical twins. Therefore, identicals cannot be said to "run" in a family, and anyone can have them!
Twins are awesome. Congrats Annette!
