Baby's heart beat

Good day to everyone!  Went to the OB yesterday and baby's heartbeat is 166-170 (12 weeks 3 days, hearing it for the first time).  It took a couple of minutes, but we found it.  The OB was nice enough to find a heartbeat that sounded "close".  He found it and it sounded "distant" at first.  Baby daddy heard it before the OB and kept saying funny comments that made me laugh and the OB laugh.  It was sweet seeing him smile from ear to ear and ask questions to the OB.  How was your first time hearing your baby's heartbeat?
