When does the spontaneous swallowing function recover in premature infants?

Preterm infants typically recover their independent swallowing function within 1-3 months, although the exact time may vary. If any discomfort symptoms occur, it is recommended to seek medical attention at a hospital promptly and follow medical advice for treatment.

For preterm infants with a gestational age over 34 weeks, due to their relatively more mature nervous system development, they may be able to start attempting independent swallowing within one month after birth. If the preterm infant does not have severe complications such as respiratory distress syndrome, infections, or other organ system issues, their independent swallowing function may recover more quickly. These infants may gradually regain their ability to swallow independently within one month after birth.

If the preterm infant's condition is more severe, with slower physical development and improper daily care, recovery of the independent swallowing function may take longer, usually around 3 months. This is because the infant's physical development is relatively slower, and without effective training and care, the recovery of swallowing function may be further affected.

It is recommended to conduct swallowing function training under a doctor's guidance to ensure the scientific and effective nature of the training. In daily life, parents should pay attention to the preterm infant's nutritional intake and oral hygiene, avoiding irritation or damage to the mouth and esophagus caused by food residue or foreign objects.
