i just got back from the doctor. we got to hear the heartbeat today! at first they had a hard time finding it so that scared us a bit...but they finally found it and then our little one didn't want to sit still long enough to hear a full min. so they had to keep chasing him/her around and starting over. we finally got a full min count in and the nurse said it was 160 beats per min. it was so great to hear that sound, it just really drives home the fact that there is a baby growing and living in there.
