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.
Nocturnal asthma is another common cause of nighttime coughing in children. Coughing occurs at night primarily because of changes in the airways that occur with sleep. An asthmatic cough tends to be a dry, hacking cough and is frequently accompanied by wheezing.
This type of croup is thought to be caused by an allergy or by reflux from the stomach. It can be scary because it comes on suddenly, often in the middle of the night. Your child may go to bed well and wake up in a few hours, gasping for breath.
