If you are using your hands to express your milk, you can tell that your milk is empty by the change in the amount of milk, the shape of your breasts, and the feeling of the woman herself. 1. Changes in the amount of milk produced: If the amount of milk produced decreases significantly or is even absent when the milk is discharged by hand, it means that a large amount of milk has already been discharged and has been emptied. 2. Breast shape: When the milk is emptied, the breasts will change from a full shape to a soft shape, which can be reasonably judged by the shape of the breasts. 3. Women’s own feeling: When there is a lot of milk, women will feel the feeling of fullness, when the feeling of fullness disappears, it means that the milk is about to be emptied. It is recommended to keep your hands clean when emptying the breast milk by hand to prevent the breast from getting infected with bacteria and mastitis. If the condition of milk stagnation persists and cannot be relieved, it is recommended to consult a doctor in time for reasonable treatment.
