Hi - thanks so much for answering this question.
My daughter (6 months) wakes up every morning with phelgm in her nose and throat. She has 2-3 productive coughs, and then it's gone for the day. Every now and then, I'll see some clear discharge from her nose, but not much.
She is not vaccinated, and my fear is that the phlegm is being caused by some bacteria that could lead to invasive Hib or strep pneumo. I don't really know how that works - whether they carry it and then it causes a problem at any time, or whether it causes a problem right away if it's going to.
My ped thinks it's just burped up milk that's collecting in her throat at night, but one time she actually coughed it out, and it's light yellow in color.
Do you have any ideas on what this could be? I of course go to the worst case scenario - like leukemia or something.
It probably wouldn't be a bacterium. Those usually either do nothing or make you sick, not just mild symptoms like your are describing. So, I don't think this is anything to figure out. It's hard to say what it might be exactly. Maybe a mild allergy to something in the bedroom.
