Bordering on dangerous levels of exhaustion

The baby has been sick since Thanksgiving. We went to the doctor yesterday and were told he has a cold. To just do all the stuff a mom of 6 kids already knows to do (humidifier, baby vicks, saline, booger sucker etc). I was really hoping for some medication to make this stop. I haven't slept more than 2 hours at a time since Wednesday night. I am writing this to document for my future self. To see how long I can truly go without sleep. I am exhausted, but happy and fulfilled. But what I wouldn't give for a full night of uninterrupted sleep.
