The third trimester of pregnancy is the stage of baby's rapid development and weight gain. The brain, bones, capillaries and muscle tissues are fully formed, the organs grow and develop perfectly, the skin becomes firm and tight, and subcutaneous fat increases. The diet in the third trimester should be based on a small number of varieties, which should not only ensure the quality but also control the quantity. Protein and the supply of high-fat food should be controlled moderately. Generally, we should adopt the method of eating less and more meals, and eat more small and nutritious ingredients. Eat less bulky and low-nutrient ingredients, such as potatoes and sweet potatoes.

The miscellaneous grains suitable for pregnant women are corn, sweet potato, black wheat and black rice. The 28th week of pregnancy belongs to the second and third trimester, and the growth rate of the fetus is accelerated, so it is necessary to supplement enough nutrients to meet the requirements of pregnant mothers and babies. It is suggested that pregnant mothers have balanced nutrition at this time, eat less and eat more meals, be picky about food, and eat less fried or high-calorie spicy food. Enter the perinatal period. The state stipulates that the perinatal period starts from the 28th week of pregnancy, and all abnormal phenomena should be solved in the hospital as soon as possible, and it is necessary to ensure that the α -linolenic acid and fatty acids needed for the rapid growth and development of the brain are sufficient in the next three months. Only deep-sea fish have it, so it is best to eat seafood products every week and eat more watermelon and dried fruit ingredients to reduce the life of couples.

In fact, it is necessary to reduce the life of husband and wife between seven and ten months of pregnancy, and completely ban the life of husband and wife six weeks before delivery to prevent premature babies from preventing diseases. In the third trimester of pregnancy, it is necessary to carry out pathogen shaping test to see whether mycoplasma, chlamydia and non-gonorrhea are infected, so as to clarify the physical condition of pregnant women before delivery and prevent vaginal inflammation during this period. When the pregnant mother reaches 28 weeks, the baby grows up slowly, occupying all the area in the mother's stomach. Mother's organs will be crowded together. At this time, my mother will feel breathless and sometimes panic. If it does happen, don't worry, mom. This is also a problem-free situation within 28 weeks. At this time, mother should not let herself be too tired, take more rest, and try to let others do the housework at home. Mom doesn't have to go to crowded places, where the gas is not circulating, and mom is very prone to syncope, which is very easy to squeeze into the baby.

At 28 weeks of pregnancy, mothers are very prone to premature delivery. At this time, if the mother has strong uterine contraction or vaginal bleeding, and the pressure in the lower abdominal cavity is too high, it is very easy to produce premature babies. Mothers must pay attention to their physical changes, especially the baby's fetal movement. If you find abnormal fetal movement, you should go to the hospital immediately. When the baby is 28 weeks old, it has grown and developed completely. At this time, the baby is more cheerful, sometimes stepping on the mother's stomach and interacting with her mother. In some cases, I am curious about the fetal umbilical cord, but at this time, with the risk, if the fetal umbilical cord is too long, it is very easy to have the risk that the fetal umbilical cord will wrap around the neck, resulting in insufficient oxygen for the child, and even more serious, ventricular breathing will occur. If the baby has an accident and such a thing happens, the mother will go to the medical institution to solve it, which is likely to lead to an early cesarean section. Therefore, mothers must do more pregnancy tests to ensure the baby's physical and mental health.
