Late preterm birth: Born when the fetus is 34 to 36 weeks and 6 days. Although the survival rate of premature babies is gradually improving with many scientific advances. However, premature babies still face many problems such as cognitive retardation, cerebral palsy, epilepsy,... The baby's lungs are not mature enough when born prematurely, therefore, the risk of diseases respiratory such as pneumonia, bronchitis,...is very high.

2.3. Premature birth due to placenta previa, placental abruption. Due to placental insufficiency, nutrition for the fetus is inadequate. Due to early departure from the mother's womb, the body is weak, and premature babies are difficult to survive or survive, with the risk of mental and physical sequelae. In addition, premature babies are also difficult to raise, often underweight, slow to grow, and parents have to spend a lot of effort to take care of them.
