There are various options available for inducing labor. In either case, a combination of treatments might be required and it depends on each individual based on different criteria. The time period it takes for the baby to be born post inducing labor might range from a few hours to as long as 2 to 3 days. This depends on how your body responds to the inducing of labor. Also, in cases of first pregnancy or if it is less than 37 weeks of pregnancy, it is likely to take much more longer.
