Now that's reason to celebrate - a snow day AND a heartbeat.
Our little pumpkin was moving around so much she had to chase him/her with the doppler. We kept hearing little kicks. The midwife said s/he was very active. We like to think there was some dancing going on, as we had just been boogeying down in the car. It really is a sound I will remember forever.
I concede, second trimester AND a heartbeat. It's time to relax and enjoy.
