The most important symptoms of a baby’s watery condition are: first, poor digestion, diarrhea, vomiting and, in severe cases, dehydration. For such children, the main thing is to pay attention to dietary hygiene. In addition, after going to a new place, eat as little local food as possible, so that the child’s gastrointestinal tract has a gradual process of adaptation, and then gradually increase the local food and water after adaptation. Second, local skin allergies may occur, which is one of the main manifestations of discomfort. It is common for children to have skin allergies because they are not accustomed to the local environment or climate, so they can be given oral anti-allergy medication. In addition, avoid eating seafood and other high-protein foods as much as possible, eat more vegetables and fruits, and drink more water.
