28424 Prenatal Listening System IB p3.1.pdf
Sound Guide:
Fairly steady, rapid drumming. This is the sound of your baby's heartbeat. It is not unusual for the pace of the
heartbeat to vary while you are listening.
Strong thump. You've felt your baby kick and now you may be hearing it, too.
Multiple thumps. Your baby may have hiccups. Hiccups are typically 3 to 5 seconds apart. You may feel these thumps
as your baby moves with each hiccup.
Growling. This is your stomach growling or your intestine gurgling. These noises are not associated with your baby.
Soft rumbling. If your baby is not in an optimum position for listening, you may hear a low rumbling sound. Try again
later after your baby has shifted. If you are in the early stages of your pregnancy, you may also hear this sound. The
system usually can begin to detect your baby's heartbeats at the beginning of your third trimester - typically around
28 weeks.
Your heartbeat. You can also listen to your own or your child's heartbeat. In this case, you can hold the sensor to
your chest, or your child's chest, with your hand.
Factors Influencing The Ability To Hear Your Baby's Heartbeat:
Please be patient when using this product. Do not be alarmed if you are not able to hear your baby's heartbeat and
movements right away. The more you use the system, the easier it will be to find your baby's heartbeat. The optimal
time to listen to your baby's heartbeat is a couple of hours after eating. Best results are found when you are
completely relaxed in a quiet room. The following factors can also affect when and how well you will hear your baby's
heart beating.
Stage of Your Pregnancy
The system will usually begin to detect baby sounds at the beginning of your third trimester - typically around 28
weeks. At this stage of your pregancy, adjust the position of the sensor so that it is between your navel and pubic
bone. As your baby grows, you will hear its heartbeat with the sensor farther up your abdomen, closer to your navel.
Baby's Position and Activity
Your baby is quite active and moves often. It is not unusual for your baby to move into a position where the heartbeat
cannot be heard, especially during the earlier months of your pregnancy. If your baby moves while you are listening,
simply change the position of the sensor or try again later. If your baby is particularly active, the kicking sounds may
make it difficult to hear the drumming of the tiny heartbeats.
Mother's Weight
Your weight before and during pregnancy may affect how early the system can detect your baby's heartbeat. A slender
mother will generally hear the baby's heartbeat earlier in her pregnancy. This is a passive listening device and,
therefore, it has no means of penetrating your body's insulating layer of fat. Mothers with a larger percentage of body
fat may have to wait a few more weeks until the baby's heartbeats become strong enough to be heard.
Mother's Position
You can hear your baby while lying or reclining in bed, on a sofa, or in a recliner with your upper body elevated by
pillows. For comfort, elevate your right hip and/or knees with a small pillow.
WARNING: Avoid lying flat on your back for an extended period of time during pregnancy, especially in your last
trimester. Check with your health care professional for recommendations on this matter.
Battery
The system operates on a standard 9-volt battery. If the light does not illuminate when the earbuds are connected, try
disconnecting and reconnecting the earbuds jack. If the light still does not illuminate, your battery is very low or
completely drained. A standard battery will last 10 to 15 hours under normal use. For best results we recommend the
use of an alkaline battery.
Note: The Prenatal Listening System is a fun, recreational device for listening to your baby's sounds. It is NOT a
medical device. It should NOT be used or relied upon in any way for diagnostic or other medical purposes.
