Expectant mothers like to give birth to their children at specific time. Some may want their child to be born naturally on a specific date or feel giving birth rather than holding on to the baby inside by caesarian. The reasons for opting for caesarian may vary. A mother would be sick of being pregnant and would want to move on with having a baby. It could just be the fear of giving birth to an overdue baby as well. In any of these circumstances it might be needed to naturally induce the baby to be born without making a large influence greatly which could harm the baby.
