We welcome the comments of Hatherill et al, because they agree with our main contention,1 ie, that the current practice of administering hypotonic maintenance parenteral fluid therapy to children can lead to dangerous hyponatremia and is in need of change. Where we differ, however, is in how we propose to change it. Hatherill et al suggest reducing the volume of maintenance fluid rather than using isotonic saline.2 Although it is true that fluid restriction will prevent hyponatremia, we are concerned that this practice could cause harm by perpetuating a state of subclinical volume depletion. Volume depletion is common in children
