The Time Traveler's Wife--spoiler alert

So, I loved this book when a read it 3 or so years ago, but I had forgotten a very important part of the story line. When Henry and Clair are trying to get pregnant, the baby has this same anomoly as it's father--chonologically challenged. They miscarry several times because the baby time travels from utero and therefore cannot survive. I felt so bad taking Justin to this movie. I really liked to movie, but this aspect of the plot was very difficult.
