The Food and Drug Administration is warning parents not to give small children over-the-counter cold and cough medicine.
The advisory comes as part of a broader review of the safety and effectiveness of those drugs in kids under age 2.
The FDA has discovered serious problems can develop if too much cold or cough medicine is given, or too often, even if it says it's for kids on the label.
Instead, the FDA says children under 2 should not be given over-the-counter cold remedies unless it is under a doctor's supervision.
Also the government advisors say don't use a teaspoon. If the medicine comes with a measuring device, use that because it will be more accurate than a teaspoon.
