Here is a quick example, the kids are staying with my mom again (hubby is not doing well) and my 3yo son has quite the head cold. Everynight before bed she does this, no coughing all night. Last night she did not, she listened to him cough for about 1/2 an hour befor she got up and put it on. Not another cough for the rest of the night.
