1. Supplementing adequate nutrition: Scientific research shows that the division and proliferation of brain cells are mainly completed in the fetal period, and it has two peak periods. The first peak period is 2 ~ 3 months of pregnancy, and the second peak period is 7 ~ 8 months of pregnancy. If the division and proliferation of fetal brain cells tend to peak, it can lay the foundation for children to have high IQ. Therefore, pregnant women should pay special attention to the intake of nutrition in these two stages of pregnancy to ensure that the baby's brain has enough nutrition. There is a flesh-and-blood relationship between mother and fetus. The emotions of expectant mothers during pregnancy are transmitted to the brain through the mother's sensory organs, and then the mother's psychological activities affect the physiological situation, and finally affect the fetus. Therefore, the change of mother's feelings will be transformed into thinking information and transmitted to the fetus, thus affecting the fetus.

2. Proper exercise during pregnancy is of great benefit to physical and brain development. When pregnant women exercise, they can provide enough oxygen and nutrition to the brain, promote the brain to release enkephalins and other beneficial substances, and enter the fetus through the placenta, which is conducive to the growth and development of the fetus; In addition, pregnant women's exercise makes amniotic fluid shake, and the shaking amniotic fluid can stimulate the whole skin of the fetus, just like massaging the fetus. These are very beneficial to the brain development of the fetus and will be smarter after birth. Sleep more than usual during pregnancy 1 hour or so. Adequate sleep is very important for pregnant women. Lack of sleep will not only affect mood, diet, work efficiency and psychological state, but also affect fetal development through some hormones related to mood. The fetal organs are not fully developed. If the mother doesn't get enough sleep, it will affect the development of the baby's brain and height.

3. Have a sense of ceremony in life: Many parents ignore the sense of ceremony too much. They always feel that life is dull and there are too many things to be taken seriously. But in children's eyes, the sense of ceremony can often bring them great happiness and leave the best memories. Parents can't ignore the importance of a sense of ceremony. Sometimes even a small ceremony can bring a great sense of security to children. For example, if a child is going to kindergarten, parents can prepare a small ceremony for the child to celebrate his growth.
