When will I get to hear baby’s heartbeat? What does the heart rate mean?
Your OB will probably listen for the heartbeat with a Doppler ultrasound device around week 12. (Some of our mom friends have had doctors try a little earlier, but usually not before week 10.) Anything between 110 and 160 beats per minute is considered "normal." And though we’ve heard many a grandma claim that the heart rate can reveal baby's sex, scientists say no way. In fact, the heart rate changes a lot -- even baby wiggling around can speed it up. (But if you want to play along for fun, the old wives' tale is that girls have faster heartbeats.)
