The plague returns

I'm back home again with DOM, who has managed to contract the latest ick going around day care. She has managed to combine a series of illnesses in one big, goopy mess. She has conjunctivitis, an ear infection, congestion, and a stubborn fever. I would like to thank the parent in her day care who sent their child in with pink eye so that she or he could share this lovely experience with the entire class. It's not gum, people - you don't have to share with everyone.

The books say that these childhood illnesses are frequent in group care settings until they start to build up immunity to the various germs and viruses. So, uh, when exactly is that going to happen?
