A. You are describing a very classic case of daycare syndrome.
Young children in daycare very often get frequent upper respiratory tract infections, including colds and secondary ear infections. Fortunately, the longer they are in daycare, the fewer infections they usually get. And by the time they start kindergarten, these children seem to get sick much less often than children who weren't in daycare and rarely got sick as a toddler or preschooler.
If she is otherwise growing and developing normally, hasn't had any serious infections, like pneumonia, or other infections that required hospitalization, than it isn't very likely that she has any kind of problem with her immune system causing her frequent infections.
According to the Jeffrey Modell Foundation, warning signs of a primary immunodeficiency can include:
- eight or more new ear infections in one year
- two or more serious sinus infections in one year
- two or more months on antibiotics with little effect
- two or more pneumonias within one year
- failure of an infant to gain weight or grow normally
- recurrent, deep skin or organ abscesses
- recurrent thrush in mouth or elsewhere on skin, after age one
- need for intravenous antibiotics to clear infections
- two or more deep seated infections
- a family history of primary immunodeficiency
