When a small baby develops food poisoning, the first thing that manifests itself is the symptoms of the digestive tract. At first, abdominal pain is the main symptom, which the small baby cannot express, and usually expresses itself in a rolled-up abdominal posture and crying posture. If the baby’s abdomen is pressed or stretched, it will cry more, and this situation represents the manifestation of abdominal pain. Next, there will be nausea, vomiting, diarrhea, etc. If the diarrhea and vomiting are more intense, there may also be symptoms of general dehydration, such as drier skin and collapsed eyes. If the toxicity of the food is absorbed through the gastrointestinal tract, thus spreading to the whole body, it may also invade the central nervous system, and there will be a poor mental state, and in serious cases, coma, convulsions, shock, etc.
