Very sad question :'( ?

2 years ago my wife and I went through the same thing. After multiple ultrasounds and amneos We were told our baby boy had trisomy 21 (downs) as well as an in utero virus that causes blindness and very severe mental retardation. When we first found out we were devastated. We contemplated terminating the baby. The more friends and family told us we should abort the angrier we got. He was our baby boy and he needed us just as much as his big brothers. We delivered our perfectly healthy Rocco Armando in March of 07. Not only is he free from any disabilities he is extremely gifted in comprehension, speech, size, strength, and body control. Way ahead of his 2 older brothers at the same age. False positives happen all the time. So the way I see it for your friend a year with her beautiful daughter (hard as it may be) with the chance that she could be healthy like my roc far outweighs the agony of terminating the pregnancy and never knowing what could have been. If I had made that choice I would be haunted by it. Best of luck
