So, last week I rented a Fetal Doppler Heartbeat Monitor so that Laura and I could hear the heartbeats coming from the twins.  It was delivered yesterday, and we gave it a try.  Here are two MP3s that I made of the heartbeats.  In the second one, you can hear Andi saying that she thinks it sounds like a dog.  I think she was referring to the sound of a dog panting.  🙂
