1) The child is not hers, but is somebody else's. This is based on the photos showing little or no evidence of pregnancy well into the third trimester.
This school of thought (which I don't subscribe to) could easily be ended with the production of a birth certificate. It is not a credible scenario, though.
2) The child is hers, and she managed the last stages of her pregnancy responsibly and with full approval of her doctor or doctors. This is almost as unlikely as scenario number one, as the statements by her physician fail to meet such a standard as a description of full approval of the patient's conduct, particularly during the final days of pregnancy. This is not a credible scenario.
3) The child is hers, and she acted irresponsibly during the final stages of her pregnancy, with a full schedule of events and with extensive travel which no reasonable doctor would have advised for a woman carrying a fetus all but certain to be a special needs child. This is the most likely scenario, and the one I subscribe to. It is also a scenario in which she actually, in my belief, hurt the child in a way that injured him for life.
4) The child is hers, and once she realized he was most likely a special needs child, she was determined to both keep the pregnancy secret (which she certainly did) and to do everything possible to miscarry the fetus (which is quite impossible to totally rule out).
I have been rather surprised by the number of obstetricians and delivery room medical professionals I've encountered over the past 16 months who believe this to be the most likely scenario. Understandably, none are willing to come forward on this at this time. Although I don't subscribe to this view, it cannot be ruled out.
However, it is a more likely scenario for the baby than this one:
The America I know and love is not one in which my parents or my baby with Down Syndrome will have to stand in front of Obama’s “death panel” so his bureaucrats can decide, based on a subjective judgment of their “level of productivity in society,” whether they are worthy of health care. Such a system is downright evil.
