1. You cannot hear your unborn baby with your Prenatal Heart Listener
®
.
a. It may be too early in your pregnancy to hear your baby. Wait until
you are in your third trimester when the fetal heartbeat starts
becoming louder.
b. It is quite normal not to hear your baby due to her position. Try
again later. The best time to listen is 3 to 4 hours after a meal and
when you are relaxed. You may also want to try placing the Prenatal
Heart Listener

against your lower back as this may help minimize
interference from your own body's sounds.

wheel to the right until you hear a click and the red power indicator
lights up.
