Coughing

So today Jesse has decided to stay home with Bella.  It's been a toss up as to whether we should keep her home from school or not this week.  The nights have been horrible, but the days aren't quite as bad.  Yesterday she did end up going to school, and since I didn't hear from the teachers the day must have gone alright.  But when Jesse picked her up from daycare last night, she didn't want to eat and fell asleep in his lap.  She proceeded to take a two hour nap, and when she woke up, she still didn't want dinner, or even anything to drink.
Just to show you what our typical nights have been lately - last night:

Bella went to bed around 9pm (a little later due to the extra nap)
1am Bella wakes up coughing, her coughing is so bad that it goes on forever and for minutes at a time I am pretty sure she can't really take a good breath.  We had her swabbed for whooping cough at the doctors, even though they didn't think it sounded like she had it.  If she did have it, we would find out today.
1:15am we get Bella back asleep
1:20am back up with coughing fits again
1:25am Bella is sleeping again
1:35am back up with coughing fits
1:45am Bella is sleeping agin
2:00am back up coughing again - which at this point you start getting mad and asking why she can't be allowed to just sleep
2:15am Bella is sleeping
2:30am back up coughing AGAIN, and of course each time we wake up coughing Bella is more upset, which makes the coughing worse
2:45am Bella is sleeping
3:30am back up again coughing
3:40am sleeping again
*and when I say sleeping again all these times I only mean Bella, it takes Jesse and I a little longer to actually fall asleep.  Most of the night we are actually up and listening for the coughing to start again.
5:30am coughing and crying and fussing
6:00am Jesse decided to stay home from work and take Bella downstairs and see if she is finally hungry
6:15am Bella does not want to eat or drink
6:30am Bella falls asleep on dad's lap on the couch

Yep, that's what we have been dealing with for the past 4 or 5 weeks.  And we literally have made no improvements, so it's hard to say just how much longer we are going to have to deal with this.
