No. Such women should be locked up in a mental institution because then the woman and the child could have a chance at being saved.
Locking up people in mental institutions would not increase their chances of being saved. Instead, with all the drugs administered in these facilities by psychiatrists, patients are reduced to zombies who are unable to pray due to the fluoridated psychoactive drugs, which affects the brain. I would not wish this on my worst enemy.
It would be awesome if Catholic monasteries could be set up to care for pregnant women and their children instead of institutionalizing people in mental health care facilities.
I used to visit a lady who was mentally ill. She was incarcerated in a skilled nursing facility among a normal population unaware that she had been diagnosed with paranoid schizophrenia. Her psychiatrists would discourage any practice of religion, so my friend would ask me for holy cards, religious reading materials, and rosaries, which would be taken away from her by the nurses. It was so pathetic. She died alone without a priest although she was given a Catholic funeral by her family.
