A friend of mine is about to give birth in the next few weeks. Currently the baby is in a breech position. My friend is trying to get the baby to turn around so that a normal vaginal delivery can be done.
Aside from medical advice, she has been advised to make sure that all the seforim (Jewish books) in her house are right side up.
My question is really very simple: is there some authentic Jewish source that recommends this, or is it just a bubbe ma'aseh (i.e. books turned around = baby turned around) that some old midwives came up with.
(Please no bashing here -- I'm not asking for scientific studies of whether or not making sure your seforim are right side up helps. I just want to know if there is any authentic Jewish source for this.)
