Introduction
Low milk supply during the day but higher at night may be related to factors such as poor mood, lack of sleep, and malnutrition. During the day, ensure adequate rest, avoid anxiety and irritability, and maintain a balanced, nutritious diet. It could also be associated with improper eating habits, so dietary adjustments are important to improve quality of life during breastfeeding.

Breast milk supply being low during the day but higher at night may be related to factors such as poor mood, insufficient sleep, and malnutrition. During daytime, it's important to get adequate rest, avoid anxiety and irritability, and maintain a balanced, nutritious diet.

1. Poor Mood

If women remain in a state of tension, anxiety, or depression for prolonged periods during lactation, it can easily affect milk production and lead to a gradual decrease in supply. In such cases, maintaining a positive mindset and staying cheerful each day can help improve low milk supply.

2. Inadequate Sleep

Chronic late-night habits during breastfeeding that result in sleep deprivation can impair milk production and reduce milk quality. At night, better sleep recovery may occur, which could explain the increased milk volume observed during evening hours.

3. Insufficient Nutrition

Breast milk requires substantial nutritional support. Prolonged nutritional deficiencies can lead to depletion of essential nutrients in the body, affecting milk secretion and possibly resulting in lower supply during the day but relatively higher supply at night.

In addition, improper diet—such as consuming spicy or stimulating foods—may also affect milk quality. Therefore, attention should be paid to dietary adjustments to improve overall quality of life during lactation.
