My 4 Year Old Daughter Seems To Be Constantly Getting

My 4 year old daughter seems to be constantly getting sick. Last 4 months she sick more than not. She usually starts with a runny nose, cough, fever (102. At the worst ) her eyes gunk over getting red at times, a thick mucus sometimes dark green. She has to throw it up to get it out. Her cough gets really bad at night. We almost rushed her into the er 3am the morning before we took her to clinic. Her cough finally stop to a normal Level. 4/6/16 she was at the clinic diagnost with bronchitis. She today is showing signs of being sick. I'm stumped and sad.
