Babies can’t suck on the nipple, can be improved by adjusting the feeding method, adjusting the feeding posture, increasing the frequency of feeding and adding formula milk if necessary. 1. Adjust the feeding method: the baby must hold more than 2/3 of the areola when sucking, and at the same time, the chin is close to the breast to ensure effective sucking. 2. Adjust the feeding position: If the child often chokes when lying down, it may cause the child not to suckle breastmilk, at this time, you can take the baby to elevate the upper body, to prevent choking, etc., to change the feeding position, part of the baby will be able to suckle breastmilk. 3. Increase the frequency of feeding: there are some small babies sucking ability is relatively weak, after a short period of sucking feel fatigue, you can increase the frequency of sucking, so that the child gradually exercise their ability to suck the breast, so as to achieve the purpose. 4. Add formula: If after repeated attempts, the child still does not suckle the breast, then you need to add formula to prevent prolonged starvation leading to hypoglycemia, malnutrition and so on. There may be other ways to improve a baby’s ability to suckle, but if the symptoms are long lasting and obvious, it is advisable to consult a pediatrician and receive professional advice from a pediatrician.
