Should alcohol consumption be illegal during pregnancy?

So for my Child Development class this morning I had to answer the following question:
Now that you know that the leading cause of mental retardation (alcohol consumption during pregnancy) is completely preventable, what do you think are appropriate procedures to implement in order to help avoid such birth defects?

Should alcohol consumption during pregnancy be limited by law? If so, how? If not, why not? Why do you think this is this such a controversial subject?

Are there other legislative issues that you think ought to be considered when it comes to protecting the developing fetus? What should the rights of the mother and father be during the prenatal period?

Here is my response, what do you think?

I am really torn on this issue. I want to be able to say, “ yes make alcohol consumption during pregnancy be completely illegal.” Then I start thinking about the babies of those mothers who are already born a step behind everyone else; would it benefit them to have their mom go to jail? Chances are that the baby would then go to family member and be raised. But what if the baby goes into foster care? Some of my friends that have been in foster care, would of rather stayed where they were because it was so bad. If you don’t step in though the baby already born with FAS (probably) is now living in a house where one or both parents (if there are two) are alcoholics and that is not good either. Like the book said the most important part of the developing fetus is the first few days and weeks after conception when Organogenesis happens and most women don’t know they are pregnant at that time, so would it help to put them in jail after the baby is born? There are already so many non-special needs kids waiting to be adopted by families, it takes even longer for special needs children. The hard part is that we all want to prevent birth defects, we all want healthy happy babies and to what extent will we go to achieve that?
The best thought I can come up with at this point is that the mom’s should go to a rehab facility. If they have family that is sober, have the baby stay with them, if not mom takes that baby with her and people there take care of the baby while mom works on herself. (meaning baby and mom live together with other babies/moms, but sitters are provided when mom’s go to therapy or need to be elsewhere) I just think that so much can happen in jail, you want the mom somewhere safe and you want the ultimate goal to be for mom and baby to, if nothing else, be in each others lives.
