K.E.
I have not gone through this situation myself, but a friend of mine had said something to me that fits. What would she do if the results were not favorable? Would she term. this pregnancy? If not then what is the point of risking it for the knowledge. If she has the room in her heart to love this baby faults and all then there you go, But if she know in her heart that they would not make good parents of a "special" child and cannot afford all the medical, then she might want to get the amnio. This gives her the answer, all clear or need to save $$$ get better job or term. what ever her choice may be.
This is a hard thing to discover about yourself, but it is something we all need to know when facing a situation like this. Can we handle a "special" child.
I hope this has helped and please do not judge her if her desicion is not what you would make for your self, we all have our limitaions and she needs to recognise them with your support.
