I'm not a doctor, and I don't have any statistics in front of me, but what's the actual percentage of high-number multiple births (four or more) that result in disability? I understand that carrying five, six, seven, eight kids is risky - and that that's a massive understatement. But I also know that the last couple of octuplet sets were born generally healthy. So did this woman kill three of her children because of the risks or because she didn't want to deal with five babies?
If I seem callous or cruel, please understand, questioning someone's motives is not nearly as callous and cruel as torturing an infant to death.
