According to the relevant regulations of civil aviation, babies born for 14 days and in good health can take a flight, the details of which can be found on the official website of civil aviation or by calling civil aviation. Since the lungs of newborn babies are not fully opened, and the capillaries are fragile, and the body’s tolerance to changes in gravity and air pressure is weak, all newborns within 14 days are not suitable for air travel, and it is recommended to wait until 4-6 weeks later. In addition, when the baby is sick or has a fever and other symptoms, is also not suitable for air travel. Wait until the infant’s physical condition is relatively stable, and the diet and digestive function have improved significantly before flying. When flying, parents need to pay attention to the physical condition of their children. Infants should not eat too much before flying. When the plane is flying smoothly at high altitude and after landing, infants can be fed milk or water appropriately, and the sucking action helps balance the pressure inside and outside the ear and relieves the infant’s eardrum discomfort.
