Feed from only one side at night, and use a breast pump on the other side.
Under normal circumstances, when feeding at night, only one breast is used while the other usually needs to be emptied. If the unused breast is not properly drained, various issues may arise. The specific analysis is as follows:
If only one breast is used during nighttime feeding and the other is not emptied, it may lead to excessive milk production and subsequent reduction in milk supply (milk regression). Consistently leaving one breast full can stretch the breast tissue, resulting in asymmetry—where one breast becomes larger than the other—thus affecting appearance. Prolonged milk accumulation also increases the risk of blockages, which may trigger inflammation and lead to mastitis, causing symptoms such as swelling and pain. Therefore, it is recommended to fully drain each breast after feeding. Ideally, alternate breasts during feedings, as a baby's sucking helps stimulate milk production. If the baby frequently nurses on only one side while neglecting the other, milk supply in the unused breast may significantly decrease. Breastfeeding mothers should pay attention to their diet, focusing on warm, easily digestible foods, and avoid spicy, stimulating, or cold foods to prevent adverse effects on the baby’s health.
It is also advisable to consume more protein-rich foods such as lean meat, fish, shrimp, and milk, which help nourish the body and enhance immunity.
