> Even the justifications that are possible
  > treat women like children

There are plenty of cases where social convention and/or the law treat adults like children. This, to me, seems like something that only happens to be aimed at women because they are the only ones that get pregnant. This doesn't seem like a social convention that is targeted explicitly at women because people believe that women have no self-control, and would do keg-stands while pregnant if we didn't hold them to task.
