Eating ghee and butter will smooth the delivery.
There is small element of scientific fact in this. Ghee and butter irritate the intestine and cause loose motions. The same nerve supply to the intestines also supply to the intestines also supplies the uterus which then starts contracting and these pre-labor contractions soften the cervix or mouth of the womb, which makes for an easier delivery. By the same rationale, obstetricians give their patients castor oil around the due date so as to encourage uterine contractions and induce labor. If your weight comes under a reasonable limit, you can have ghee, if not, stay away. Check with your doctor and practice moderation.
