We all know that babies have different personalities and temperaments.  While one baby may be able to self soothe, another may require much more attention to calm and relax.  One may enjoy bath-time and squeal with delight; the other may scream when their toes touch the water.  While there isn't a magic formula for the perfect baby, we can influence them even while in the womb.  Studies have shown that mothers who have used a prenatal curriculum such as BabyPlus have babies with an increased ability to self sooth and are more relaxed and alert at birth.  It doesn't guarantee that your baby will sleep all night, will never cry, or will be a genius, it just means that you have given your baby a head start by using the one constant they experience throughout their nine months--their mother's heartbeat.
