If the baby has a fast heart rate, greater than 140, it is a girl. If the heart rate is less than 130, it is a boy. Variations in heart rate can provide information to health carers like whether baby is asleep, awake, healthy or distressed but not gender. If you crave spicy foods, it's a girl - bland foods, it's a boy. If the baby kicks before 20 weeks it's a boy.
Baby boys are harder to birth than girls.
If the baby kicks in response to intercourse, lovemaking should be avoided. Abstinence is only recommended when there is a threat of miscarriage or premature labour. If you are faced with a frightening sight, put your hands over your navel, so that baby won't see. Many cultures believe that unborn babies are influenced by the emotional environment of the mother and this is gaining credence among western scientists. When stress hormones like adrenalins are released into the mother's blood stream, they are absorbed by the baby too.
