A Penn State study found that honey was more effective than dextromathorphan for treating nighttime coughs in kids ages 2-11. The dosages used in the test were equivalent to the cough syrup: half a teaspoon for kids 2-5, a full teaspoon for kids 6-11.
Both parents and kids reported better sleep quality. Kids reported they liked the bear-shaped bottle. Also, remember that episode of ER? Don't give honey to a kid under 1yo.
