The infant is experiencing vomiting, diarrhea, and watery stools—likely due to viral gastroenteritis causing gastrointestinal dysfunction. If the infant develops severe diarrhea, prompt medical evaluation at a hospital is essential to determine the underlying cause and initiate appropriate treatment. Prolonged diarrhea may lead to dehydration and electrolyte imbalances; intravenous fluid replacement is often required in such cases. In daily life, attention must be paid to food hygiene—especially regular disinfection of the infant’s pacifiers, bottles, and utensils.
