When we moved to the US in 1984, I was expecting KJ already, and I was told he was due around April 10. At my first appointment and ultrasound in the US, I was told I was due on the 25th, two weeks later than I had been told in Japan. Being the obedient person I am, I went into labor on the 25th, and after several hours spent walking in figure 8's through Aunt Nancy's kitchen, family room, and dining room, the family made me get in the car to go to the birthing center.
Once there, the doctor felt I would have Keishi for several hours, and told Nancy she could go to her class and be back in plenty of time. Of course he was born about 15 minutes later, probably before Nancy even got out of the parking lot.
Because of the calcification of the placenta and how wrinkly he was, they told me he was at least 2 weeks late.
