Man, if I had octuplets on top of having six kids already, I'd shoot myself.
I suspect she doesn't believe in abortion (or "weeding out" the embryos that have attached to the uterus lining), which is the reason for having all eight babies. My understanding is that the put so many embryos in because usually not all of them attach, so they want good odds of at least one attaching.
I think it's a big stretch to jump from "mother of six has eight babies" to "OBVIOUSLY a poor single mother who is going to live off welfare!!" First of all, she's not single; the husband is a contract worker. The CNN story doesn't word it well, so I can see why people would think it was the grandfather in Iraq instead. But at the top of the story it says, "The father, a contract worker, is due to return to Iraq, mother-in-law says." Second, if she can afford fertility treatments, that's a good indication she isn't poor. Those things cost $$$.
Personally, I think taking fertility drugs is a poor idea when you already have six children. Actually I think fertility drugs are a bad idea, period. I can't imagine the insane amount of work it will take to raise eight infants on top of six two- to seven-year olds.
