CROUP - A condition where the voice box (the part of your body that your voice comes from) in your throat is inflamed. This is usually caused by an infection. You will notice this most often when you get up in the morning. Breathing will be harder, your throat will be dry and tight and you'll have a barking type cough. What your parents might do for this is put you back in your bedroom and turn on the humidifier or vaporizer which puts moisture from water into the air to help make your throat feel better.
