Thanks everyone, my DD is on the road to recovery. I, however, now have a double inner ear infection and a sore throat from the mess- I'm not great but I'm the least of it. My DS11, is a giant mess. Tuesday he came home from school with a tickle, by Tuesday night his airways so much he could barely speak (this is WHILE on all his heightened Ashma meds) had closed to the point I was seriously worried he needed an ambulance. But I had the nebulizer and albuterol right there so in 30 seconds he was improving... followed that with 10 min in a steam shower and the episode calmed down. Yesterday we were at the Dr. for DS (day before for DD) and DS is also on some high dose prednisone

AND the cough is still gaining momentum- but he says he can breathe so I am marginally calm.
Know what I learned, that there IS NO WAY to prevent the spread of an illness when a child is coughing. Sniffles yes, but a big cough, no. Even with all the bleaching, the separate bathrooms, the boiling everything in sight, keeping my DS's door shut, wiping everything down with alcohol based wipes the house, the cars... everyone still got it. As always, my poor DS is still getting the worst of it.
So now my new rule as of today is, anyone who coughs is stuck in their own room until it goes away and that includes me.
Good thing we canceled our trip ahead of the storm...
