Can babies drink water during formula milk-induced heatiness?
During the period when a baby experiences internal heat (commonly referred to as "heatiness") from formula milk, the baby can drink water, and适量 water intake brings multiple benefits, as analyzed below:

Babies experiencing heatiness from formula feeding may show symptoms such as constipation and dark yellow urine. Appropriate water intake can increase urine output, promote the elimination of metabolic waste, help relieve constipation, and make the baby feel more comfortable. Water also helps maintain normal digestive and intestinal motility functions. During heatiness caused by formula, digestive problems may occur; proper hydration stimulates secretion of digestive fluids, aids digestion of nutrients in the formula, and reduces the burden on the gastrointestinal system.
In addition, appropriate water intake helps rinse the mouth, reducing bacterial growth and preventing oral issues such as bad breath and tooth decay, thus benefiting the baby's oral health.
When giving water to a baby experiencing heatiness, it's important to ensure the amount is appropriate. Generally, the quantity can be determined based on the baby's age and weight, with small amounts given frequently preferred, avoiding excessive water intake at once, which could burden the gastrointestinal system. Also, if the baby's heatiness symptoms are severe, simply drinking water may not be sufficient to resolve the issue. Consideration should be given to changing the formula brand or consulting a doctor to implement other appropriate measures.
