The mother’s mental mood can not only affect her appetite, sleep, energy, physical strength and other aspects of the condition, but can also affect the fetal blood supply, fetal heart rate, fetal breathing and fetal movement and many other changes through changes in nerve and body fluids. Therefore, from the first day of pregnancy diagnosis, we should establish the view that “quiet nurturing of the fetus means teaching the fetus” and ensure that the pregnant woman is emotionally optimistic and stable during pregnancy, avoiding bad behaviors such as great sadness and anger, or even quarrels and fights. If the mother is in a bad mood, it may have a negative impact on the fetus. Experimental observation shows that: in the first month of pregnancy, pregnant women are overly emotional, which may lead to the occurrence of harelip; such as being frightened, fear, sadness, sadness and other serious excitement, or other reasons caused by excessive mental tension, so that the imbalance between the cerebral cortex and internal organs, the relationship between the dysfunction, causing fetal circulation disorders, and in serious cases, can directly lead to fetal death. It can be seen that although the emotions of pregnant women only belong to the category of indirect fetal education, but has a considerable impact on the brain development of the fetus, it is important to pay sufficient attention to it and do a good job.
