Infants occasionally spit up milk in the form of white tofu crumbs, mostly due to the imperfect development of the infant’s digestive system, the stomach is still immature, inhaled milk enters the digestive tract, proteins are decomposed by gastric acid and can form small clumps. If there are no other discomfort symptoms, it is mostly physiological spitting up. If infants spit up frequently, indigestion should be considered: 1. Physiological spitting up: infants only spit up occasionally, and there is no other obvious discomfort, no special intervention is usually needed, just choose the correct posture during daily feeding and pay attention to burping after feeding. In addition, it is common for babies to spit up, so mothers should pay attention to not overfeeding and overfeeding, and give babies enough time to digest and absorb. After feeding, you can hold the baby upright and pat the baby’s back to expel the air from the stomach to reduce vomiting. You can also gently massage the baby’s abdomen to increase gastrointestinal peristalsis and promote the digestion and absorption of milk. 2. Pathological vomiting: When more gas is inhaled during feeding, or affected by factors such as feeding too fast, too much milk, cold and unclean food, it may lead to indigestion or even acute inflammation of the digestive tract, causing vomiting, which can be accompanied by white bean curd-like milk residue. Vomiting caused by disease may be more frequent or accompanied by crying, bloating, diarrhea, fever and other symptoms, and it is recommended to consult a doctor promptly to clarify the cause and treat the symptoms. In addition, spitting up milk may cause choking and coughing, and may even lead to aspiration pneumonia, which is more dangerous. Therefore, it is recommended that parents pay attention to observe after breastfeeding, and if the infant has difficulty breathing, he or she needs to seek medical treatment in time.
