I don’t bug pregnant women I know with any oldwive’s tales about lifting, signs that tell the gender, etc. Such things have no scientific basis.
But, if you refer to the blastocyst/zygote/embryo/fetus as a ‘baby’ at anytime before the head crowns during delivery and a the soul descends from heaven to enter the body, you invite the forces of evil and disaster into your lives.
For the same reason, any reference to the pregnancy or the fetus MUST be followed by “keyn a hera” (very old Jewish expression, it translates to “no evil eye”). Any reference to a possible misfortune MUST be followed by “G-d forbid”. Any reference to future happiness MUST be followed by “G-d willing”.
If these things are not done, demons will infest the house. Every possible thing will go wrong. The fetus (currently spiritually vacant) can even,(necessary as my thoughts have come to dwell on a pregnant friend) G-d forbid, become possessed by a demon known as a pursuer. Pursuers try to induce a miscarriage and/or kill the mother.
Obviously the proper placement of religious talismans is helpful. A string measuring seven times around the grave of a righteous person, wrapped seven times around the mother’s belly and tied with seven knots will help keep mom and fetus safe.
Once the child is born, a red string or ribbon should be tied around the baby’s wrist. Ideally, silver coins inscribed with the names of the three angels who drove Lilith from Eden (Sanvi, Sansavi, Semangleaf)) are placed in the windows of the nursery. Some charm to repel her MUST be used.
The expectant dad is a lapsed Catholic, so there aren’t crosses and images of the Madonna all over the house. The expectant mom is an agnostic. They currently live several states away from his family. That means nobody is saying “G-d forbid” or “May all the saints preserve us” or “The Father, the Son, and the Holy Spirit prevent such a thing.”. It’s driving me nuts. I realize these things are completely unscientific. Still, if I wasn’t a few states away I’d be over at their house hanging cloves of garlic and chanting in Yiddish. I am not kidding. It’s like pregnancy activates some ancestral memory from the shtetl.
