Doctor Andrew Rochford & his wife had twins a few years ago. He says: ” When I stood next to her, I thought I understood what she went through.”...Just like w/ a ordinary 1st timer, contractions finally come more often & lasts longer. Rochford has a harder time to deal w/ the pain & begs for something for the pain. he gets nitrous oxide. After abt 3 hrs he has 60 sec long contractions & 60 sec break in b/w. That’s when Rochford had enough & stops the experiment.
