Sir.—In the September 1991 issue of AJDC, Keating and colleagues1 presented results of compelling, descriptive, epidemiologic research on the growing problem of oral water intoxication in infants.
The authors suggest that the unavailability of infant formula was a major factor in the increased occurrence of oral water intoxication and substantiated this conclusion with the fact that the current amount of formula supplied through the Women, Infants, and Children program is inadequate for the growing infant.
