The BabyPlus Prenatal Education curriculum is designed to be used during the last two pregnancy trimesters beginning at your 18th week of pregnancy.  The baby's hearing is fully developed at 18 weeks, and at that time is the only sense that your baby can fully utilize to learn about the world around them.  There are 16 lessons in the BabyPlus curriculum and each of the lessons features the same mother's heartbeat sound.  The sound varies in complexity through your stages of pregnancy and through the stages of development of the fetus.

It is recommended that the baby listen to each BabyPlus lesson for the same number of days.  So, when in your pregnancy you start to use BabyPlus will determine how many days that you and your baby will listen to each of the 16 lessons.  For example, if you begin using the BabyPlus curriculum at the beginning of your 18th week, you will listen to each lesson for 9 days.  If you begin listening to BabyPlus at the beginning of your 24th week, you will play each lesson for 7 days.  If, however, you begin using BabyPlus at 30 weeks, you will play each lesson for 4 days.  If you begin using BabyPlus as late as 30 weeks, you can listen to the lessons 3 times per day as opposed to the usual 2 times per day.   The earlier in your pregnancy that you start to use BabyPlus, the more beneficial it is to this critical period of prenatal  development.

Each BabyPlus system includes an instruction manual and a lesson calendar.  Day by day through your pregnancy you can record the times that you use BabyPlus as well as the baby's response to BabyPlus.  Many babies who become accustomed to BabyPlus will respond physically to the sound.  It becomes a special time for you to communicate with your baby.  This type of activity and the recording of the baby's responses will help you to bond with your baby, tracking his or her progress and daily activity.
