Well, I have had it all ways. With four children i have had a c-section, one natural birth with something to calm my nerves given to me through the IV, one completely natural with no pain relief or anything at all, and one with an epidural.
It is a good idea to keep an open mind....however, I will tell you my view point. Keep in mind, for all 3 of my vaginal deliveries I had no complications at all.
The most uncomfortable thing about labor, imo, is the immense pressure that you feel. When I had the epidural, it did not take that pressure away. At all. It took the edge off the pain, but it didnt relieve any of the pressure.
I went into labor thinking that I would be a peice of cake with the epidural, but it wasnt much different at all.
As women, our bodies were built to withstand carrying and delivering a child so you most certainly can do it without medication. Millions of women do it. But it is important to have a game plan and a good partner to support you through hard labor.
