Read what I wrote in #11, and keep in mind that in 1970, 28 weeks was probably more critical than 23 weeks is today.
It definitely was more critical.
BTW, mlmr, another thought: If we give the State, or the medical types, the authority to decide these kids aren't worth the investment, why shouldn't they just make the same decision about a kid who comes out at full term with spina bifida or cerebral palsy? Nice quick lethal injection, no muss, no fuss, no therapy and medical care costs...
