Baby flatulence is mainly a particularly hard and bulging stomach, and there will be a thumping sound when gently knocked. When the baby’s stomach is bloated, there will be stomach pain, discomfort, crying, etc., and some babies will have vomiting and diarrhea. First of all, we have to analyze whether there is any cause for the baby’s flatulence, such as the abdomen is cold, ate too much, too much food, or the baby ate too much milk too quickly, too fast, etc. may cause the baby’s stomach flatulence. If it is caused by cold, you can apply hot compresses to the baby’s stomach, or use your hands to massage the baby’s abdomen clockwise, which can effectively relieve the baby’s abdominal distension. If the flatulence is obvious, you can follow the doctor’s advice to apply simethicone emulsion to improve the baby’s abdominal flatulence. If the baby’s flatulence is serious, frequent vomiting, diarrhea, etc., should consult a doctor in time to avoid delaying the condition.
