Many 'experts' think you can probably get 10 days out of cold cuts if properly stored (ie: not in the bag you bought it in). For me personally, since I have a huge aversion to being sick in any way, I only would leave deli meats in the fridge LESS than one week, 4 days maximum.
Postnasal drip occurs when the nose produces excessive amounts of mucus. The mucus may drip out the nose during the day, but when the child lies down at night, mucus collects in the back of the throat, triggering a cough. Postnasal drip syndrome is a common cause of nighttime coughing in children.
Prepare your bedside. In case you start coughing in the night, have everything you need by your bed -- a glass of water, cough medicine or drops, and anything else that seems to help. The sooner you can stop a coughing fit, the better. Continually coughing irritates your airways, which can make your nighttime problem last longer.
