Giving birth to a healthy and intelligent baby should be what every mother expects. Doing a good job in diet management and reasonable exercise during pregnancy and maintaining emotional stability can not only make your baby healthier, but also make your baby smarter! Especially in the third trimester, it is the peak of fetal brain development, so we should pay more attention to it.

Adhering to the three principles in the third trimester can replenish the brain for the fetus.

After entering the third trimester, you will find that the weight of yourself and your fetus is increasing rapidly. This is the last' intense period' of the baby in the fetal period. At this time, his organs enter the stage of complete development, and the gradually mature organs will let the fetus slowly feel the outside world and enter an important period of brain development.

When a newborn is born, there are100 ~1800 million brain cells in the brain, which is close to that of adults, and the number of brain cells is fixed after birth, so it will not reproduce and grow. Therefore, the third trimester of pregnancy is a more important' golden period of brain tonic'.

1、? The principle of comprehensive diet: The development of the brain needs a variety of nutrients, including carbohydrates, protein, lipids, calcium and vitamins. Therefore, there must be enough kinds of diets at this time to ensure the development needs. Some nutritionists suggest that pregnant women in the third trimester should eat 40 kinds of food every day, at least 14 kinds. It is also suggested that the principle of nature should be the main body of the three meals structure.

In other words, eat rice, millet, corn, black beans, walnuts, sesame seeds, kelp, seaweed, apples, kiwis, lotus roots, carrots, nuts and so on. Among these natural foods, it is recommended to be the key category in your daily diet.

A study in the United States shows that pregnant women who mainly eat plant food during pregnancy may have small babies, but strong bones, and the sulcus in the cerebral cortex is greatly increased because of adequate nutrition; Pregnant women who mainly eat meat may give birth to larger babies, but there are fewer sulcus in the cerebral cortex (the number of sulcus directly affects children's intelligence and memory, and the more sulcus, the greater the memory storage). Therefore, eating more vegetables during pregnancy is of great help to the baby's brain development.

2、? Principle of reasonable exercise: insisting on a certain amount of exercise in the third trimester can not only please the body and mind, but also provide sufficient oxygen and nutrition for the pregnant mother's brain. These will further stimulate the fetus, help strengthen blood circulation and accelerate metabolism. The benefits of exercise don't stop there. Generally, exercise is done outdoors. Sunbathing can help you supplement natural vitamin D (which can't be synthesized in the body) and promote the absorption of calcium, which is a nutrient needed for fetal brain development.

In addition, during exercise, the fetus will follow the swing of the pregnant mother's body, and the amniotic fluid floating in the uterus will also contact the skin of the fetus with vibration, thus stimulating the development of the brain. This is the same as giving the baby early touching education after birth.

Exercise suitable for the third trimester includes walking, sitting cross-legged and yoga during pregnancy. , but it is best to be accompanied by family members or professionals. If you feel tired, stop and have a rest at once. If there is any abnormality (bleeding, abdominal pain), seek medical attention in time.

3、? Principle of happy mood: it is said that mother and child are connected. Actually, it started when I was pregnant. If the pregnant mother is in a bad mood, there will be more fetal movements, indicating that the baby is very concerned about her mother's mood. In the third trimester, I feel anxious and helpless about childbirth, especially prone to emotional irritability. I suggest talking to family or friends, or contacting your doctor to learn something about childbirth.

The cheerful mood of pregnant mother can deliver happy dopamine to the baby, so that she can also feel that various functions of the fetus will develop faster, including the brain.

Apart from the third trimester, when is the critical period of fetal brain development?

There are three critical periods of fetal brain development during pregnancy, two of which are pregnancy and the last one is lactation.

Before pregnancy 12 weeks: DHA is properly supplemented to nourish the development of fetal brain, which is the stage of fetal brain components;

Pregnancy 12 weeks to delivery: at this time, fetal brain cells develop rapidly and the multi-network connections of brain axons increase;

Lactation (0~2 years old): After the baby is born, it provides energy for growth and development through the supply of food. At this time, breast milk is the main source, which can promote the activity of cerebral cortex and play a role in nourishing the brain.
