A, the informant, heard this from her grandmother as well as it just being a common belief of her Jewish culture and religion. Her mother made sure never to go to a graveyard when she was pregnant with her, but she really had no reason to go to a cemetery anyways at that time.
This is a Jewish superstition that applies to pregnant women. However, I know common beliefs about this are held in various cultures concerning women not going into cemeteries when they’re pregnant.
“Pregnant women aren’t supposed to go to graveyards because apparently at the stage they’re in, they’re open to receiving demons. So if they walk through a graveyard…well…the souls are thought to enter them. Them, meaning both the baby and the mother. Then once you have the baby, it will be cursed and so will you. So…just avoid cemeteries when you’re pregnant.”
I feel like I’ve heard this before or something similar. As far as most superstitions, this one makes some sense to me. For those who really believe in a graveyard as a very spiritual place filled with ghosts, it makes sense that they would not want to expose a baby to those potentially harmful spirits. Graveyards already kind of creep me out and I do believe in ghosts, so I could see myself believing in this superstition.
