D is sick. Wet cough, high temps, general fussiness. I took him to the ped on Thursday, and they did a test for flu and for RSV. Flu came back negative, but we don't have the RSV results yet. We're doing neb treatments every 4-6 hours. Initially he was eating and drinking ok, but yesterday and today he's not drinking a whole lot (still producing wet diapers) and he's barely eating. I've tried solids, purees, all of his favorites, and he eats a few bites and then just pushes everything away. Should I try pediasure? He'll still take bottles, so maybe formula? I have some packets of the Enfamil toddler formula. Any other suggestions?

ETA: He also has a new rash on his chest and back. Just little red pinpricks. It looks like heat rash to me, but should I be concerned?
