You are not being naive at all!! I had the same experience when I was having my DD (even my mum would roll her eyes at me and say just wait until you are in labour!!) I just went into it believing that I wouldn't need the drugs and I didn't. I think most of the pain of childbirth is in our heads, once you get past that it really isn't that bad. Now I am sitting here waiting to have my second little monkey (sex UNKNOWN!!!! we choose not to find out too) and I am actually looking forward to the whole birthing process. Just relax and believe that your body can do it and you will
