First of all, I bet that was a wonderful experience being there for baby's birth. Secondly, I think you're probably right about the allergies. Hospitals tend to have very dry air - hence no dust mites or molds, so that might be a possibility. But, I wonder with your work, if the whole thing isn't being triggered by something you are exposed to, like paint. I know that's not what you want to hear, but I think its worth investigating. good luck.
