If a nursing mother eats only a small amount of tofu, it usually does not cause her child to be bloated, but if she eats too much tofu, it may cause her child to be bloated. Because breast milk may change in composition due to the influence of the breastfeeding mother’s diet, and tofu is a gas-producing food, if a breastfeeding mother eats a lot of tofu, it may cause changes in the composition of her milk and cause her child to become bloated. Tofu is mainly made from soybeans and is a high-protein food. After consumption, it is easily fermented by bacteria in the gastrointestinal tract and produces a lot of gas, which can easily lead to abdominal flatulence. When a nursing mother consumes tofu, the nutritional composition of her milk will change, and children who still need to breastfeed usually have gastrointestinal distention due to the immaturity of their own gastrointestinal tract, which may be slightly stimulated by milk or the external environment. If the child is in such a situation, you can give the child more clockwise massage of the abdomen to relieve the symptoms, or you can take drugs such as Si Mo Tang Oral Liquid and Bacillus subtilis Duplex Granules under the guidance of a doctor to improve the gastrointestinal flora and relieve abdominal distension. It is recommended that breastfeeding mothers promptly correct their diet, eat less tofu, and focus on a light diet, avoiding too much greasy, cold, spicy and stimulating food. In addition, when feeding the child, pay attention to the appropriate environment, breastfeeding on demand, to avoid improper breastfeeding leading to gastrointestinal indigestion, diarrhea and other symptoms of the child.
