Drinking a lot of water will help increase breast milk production, but drinking water alone will not increase breast milk production, and nutritional supplements are also needed. Drinking water is very important for breast milk production. If you drink too little water, your milk production will decrease accordingly, but drinking water is not the decisive factor for breast milk production, and it is related to many factors. Generally, you can promote milk secretion through babies sucking more, emptying as soon as possible, and eating protein-rich foods. You need to supplement more high-protein and high-nutrition foods, which can not only increase the secretion of breast milk, but also make the milk get enough nutrients. During the breastfeeding period pregnant women should also maintain a good mood and adopt the correct feeding method to make breast milk become more.
