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.
Sleep on an incline. When it comes to nighttime cough, gravity is your enemy. All the postnasal drainage and mucus you swallow during the day backs up and irritates your throat when you lay down at night. Try to defy gravity by propping yourself up on some pillows while you sleep.
