Did you know that the fetal heart beats twice as fast as the mother? 

A normal fetal heart rate usually ranges from 120 to 160 beats per minute when the baby is in the mother's uterus. It is measurable by ultrasound from around 6 weeks onwards and the normal range varies. It increases to around 170 beats per minute at 10 weeks and decreases from then to around 130 beats per minute at full term.
