mad i find it facinating that you cant distinguish between what we already regard as criminal neglect and child endangerment and a padded cell.
It's just the next step down the road you're traveling. But why just focus on fetal alcohol syndrome and smoking? What about Spina bifida? Women with a diet lacking in plant proteins, iron, magnesium, and niacin may be up to five times more likely to have a baby with spina bifida! A 500% increased risk just because mom didn't take the correct vitamins or eat the right food!
And what about women with gestational diabetes who refuse to go on insulin because they're afraid of needles? Their babies are at increased risk for macrosomia, neonatal hypoglycemia, perinatal mortality, congenital malformation, hyperbilirubinemia, polycythemia, hypocalcemia, and respiratory distress syndrome. Long term, they're at increased risk of developing diabetes themselves and being obese.
There is not a legal answer to every problem. Being a parent is hard enough without adding the concern of being sued because the child has some disability.
I can just see some jackass lawyer filing a class action suit on behalf of all children born with Down's syndrome. He'd bankrupt all the parents (who are, most likely, the one's supporting the disabled children.), collect millions, and then send each child with Down's syndrome a check for fifty cents. Meanwhile, the children have become homeless due to their parents having to spend their life savings in legal fees and declare bankruptcy due to the settlement.
Suffice to say, it's a very bad idea.
