Every pregnant woman faces the question of whether or not she wants to give birth naturally with no pain medication or to be medicated during child birth. And if she chooses to try medicated birth, is then faced with a host of further questions about which kind of pain relief medicines and when to administer them. I have now experienced both extremes of these choices (aside from C-section) and wanted to share my experiences to hopefully help another mom make her choice.
I'll give you my conclusion now, so that you know I have no particular agenda. I believe that this is a very personal choice and neither is right or wrong and neither is better or worse. They are simply different. Here are my two stories.

Caitlin, my first daughter, was born after our fourth trip to the hospital. I had preterm labor and was put on partial bed rest prior to her birth. On that fourth trip to the hospital, I was about to be discharged because I had not dilated and after being observed for a couple of hours and given fluids via IV, was not dilating ('progressing'). Then my water broke at 7:30 AM. So obviously they kept me in the hospital after that. It was a slow labor and while not extremely painful in the early stages, made me all sorts of nauseous. So I opted for an epidural as soon as they would give it to me hoping that it would not only stop the pain I knew was coming, but also the nausea.
Epidurals work! The pain I was having was gone, and I never really did have much pain. I say much because of what happened later. But the nausea remained. I spent the 18 hours from when my water broke to when Caitlin was born sick. Somewhere around 8 centimeters, I was told that I was not progressing
(I was not continuing to dilate at the rate they would like. If a woman stalls too much it could cause problems for the baby and that is why they were concerned.) So they administered a drug called Pitocin to speed up my labor. It did, but, it also caused contractions so hard that it was effecting Caitlin's heart rate. They gave me oxygen to help her out. I also was beginning to feel my contractions again because the Pitocin was causing me to contract so hard that it was overriding the epidural. Fortunately for us, I was far enough along that I delivered normally without need for intervention on Caitlin's behalf.
(For some women this could have led to a C-section. In fact the same thing happened to my sister when she was at 5 centimeters and ended up with a C.) Caitlin was born at 1:30 AM happy, extremely alert, and healthy.

Hayley's birth was much, much different. I did not want to have Pitocin given to me this time around. What I went through with Caitlin after the Pitocin was given to me, and what I learned about the drug afterward really scared me off of it. Again, this is a personal choice. Some women have no problems with it, but I personally choose to avoid it from here on out. I also wanted to delay my epidural so it wouldn't slow my labor down too much. I was still planning on using pain medication with Hayley, but things don't always go to plan.
When we got to the hospital, they checked me and said that I was not dilated. I knew I was in labor because of the discomfort level I was having. When they told me I was at 0, I was so worried they were going to send me home. Well, they had me walk around the maternity ward for an hour and during that time, my discomfort increased significantly. By the end of the hour I was in the bathtub trying to get some relief. I was at a 3. Ten minutes later they were trying to hook up an IV so I could have fluid and eventually get an epidural. I was so uncomfortable that she checked me again and I was at 6. They told me then that I probably wouldn't have time to get an epidural because they have to give fluid for an hour before they can administer it and I was moving very fast. Anyway, I started at 8:30 pm with zero dilation and had a baby in my arms at 10:40 without so much as an aspirin. That was the most painful experience I've ever had, but not in the way you'd expect. TV depicts the mom screaming trying to get the baby out. For me, that was the good part. I wanted to push! It was the contractions that were hard for me. I cried. But Hayley is here, happy and healthy.
If I had to choose which way I would prefer, I'd say neither. I'd prefer some mix. My ideal birth would allow me to have an epidural without nausea and not 18 hours long. But, I know that if I do have another child (And I'm not saying I am or am not. Come on! I just had one! Let me get some sleep first!) it would probably be another natural birth simply because they say after the first, they come faster. And if Hayley came that fast, I can only imagine how fast a third would be.
I really hope this post helps some first time mommies trying to make their decision or at least give them some insight into what can possibly happen. Just remember every woman, every pregnancy, every labor and birth are different and only you can decide what's right for you. Don't let anyone make you feel badly about your decision.
