About 6 months after pregnancy, the number of fetal brain cells is close to that of adults, and various sensory organs tend to be perfect, which can respond to the stimulation inside and outside the mother, especially to identify the changes of maternal mood. When the mother is emotionally stable, the fetus will feel safe; When the mother is anxious and angry, the state of the fetus is not good. This bad state is extremely unfavorable to the development of fetus and newborn. Studies have shown that the ratio of physical diseases such as pregnancy complications to fetal and neonatal dysplasia and fatal diseases is 1: 0, while the quarrel between husband and wife is 6: 0, and the despair of pregnant women is 4: 0. It can be seen that the interpersonal relationship and emotional state of pregnant women have great influence on the fetus and newborn. In order to create a harmonious environment for the fetus, pregnant women must pay attention to their mental health and psychological induction between mother and child, which is the essence of prenatal education.
In a narrow sense, prenatal education refers to the early education of the fetus through certain means, such as dialogue, touching the pregnant woman's abdomen, listening to soft music and appropriate exercise.
