How much water does it take for an infant to cause water intoxication?

Water intoxication in infants can occur with relatively small amounts of water, as their kidneys are not fully developed to handle excess fluid. It typically takes about 2-3 liters of water over a short period, but even smaller amounts can be dangerous if consumed rapidly. Symptoms may include irritability, vomiting, and seizures. It's crucial to monitor fluid intake and consult a healthcare provider if there are concerns.
