Monday morning I took him to the doctor and got a new, stronger prescription of the Nystatin. He also had to have blood drawn (that was fun since he was dehydrated) to see what his CO2 and electrolyte levels were. Turns out, they were too low and he needed IV fluids. They had to poke him twice because the first vein blew as soon as she got the needle in - again because of the dehydration. He ended up getting 3/4 of a bag of fluid over about an hour. He fell asleep with me holding him, about 20 minutes into the bag. Which was good because he wasn't very happy about having his arm strapped to a board to keep it straight.... He had a wet diaper and was cleared to go home.
Tuesday he woke up a completely different person! He actually told me he was hungry and wanted "befast" a/k/a breakfast and a "anana" a/k/a banana! Since then he has progressively gotten better and seems almost normal this afternoon.
Now we just have to break the all day tv watching. Since every time he would have a burst of energy and run around, it would make him throw up - we plopped him on a pallet in the play room in front of movies all day from Friday afternoon until Monday afternoon..... So, he thinks he's entitled to watch whatever, whenever now. OY!
