So, we bought a doppler from Amazon.com. I hate waiting in between doctor appointments, so I though hearing the baby's heartbeat anytime we wanted would help. It came yesterday and we tried it last night. We thought we found it...it sounded like a heartbeat! Apparently it was mine :( I knew it was too slow to be Baby Burns. We'll try again tonight, but I feel so silly for being all excited...about my own heartbeat, lol.
I found a cool video on YouTube of what he or she should sound like. It's also the same doppler we have:
