How much liquid can a eleven year old child's stomach hold?

An eleven-year-old child's stomach can typically hold about 1 to 1.5 liters of liquid, though this can vary depending on the child's size and individual anatomy. On average, a child's stomach capacity is less than that of an adult, as it is proportionally smaller. It's important to note that excessive consumption of liquid in a short period can lead to discomfort or more serious health issues.
