Last time we heard the baby's heartbeat (about 3 weeks ago), I decided the sound was best described as a marathon runner running while breathing into a microphone.
Yesterday we went again and the sound had changed. BJ declared that it sounded like a dog barking through a radio.
I wonder what'll it be like next time...
Update on the baby. (S)he is now 3" long (about the size of a shrimp) and has fingerprints! (No more crimes for you, little baby.)
