I know kids get sick a lot. But my friend has a son that seems to be an extreme case. He started daycare at a year when his mom went back to work and since then has been constantly sick (he was sickly before, but way worse the last year). And not just sniffles, but extreme sickness, pneumonia three times, hospitalization for kidney infection, high high fevers, etc. In the past two months he has had, RSV, pneumonia, diarrhea bug, vomiting bug, and three colds. He is honestly never healthy for more than a few days, maybe a week. The doctor just keeps brushing her off saying kids are sick a lot. But to me, this seems extreme, and that he needs some further testing. Anyone have similar experiences or know of similar situations. Could it be nothing, or should she be worried?
