DD was exposed to about 10 sick kids (visiting a daycare) on Monday. Every one of these daycare kids had thick yellow mucus just pouring out of their noses. It was quite disgusting. Didn't notice until DD had already put all the toys in her mouth and crawled around the classroom for 15 minutes exploring the environment. Yesterday morning DD woke up with a runny nose, sneezing, and spiked a 100.7 fever. She was still her playful, goofy self but just a bit cranky. Called the doc, gave her Tylenol and waited to see if the fever would clear up on its own after the Tylenol wore off. It didn't. It went up to 101.7 and lasted until about midnight last night, with a couple more Tylenol doses given to help it stay lower. When she woke up this morning, the fever was gone but she has been sleeping ALL day, waking about every hour only to take in some fluids and food and wanting to go right back to sleep. She knows the words 'playtime' 'naptime' 'snacktime' and 'bathtime' and will wake up crying, want a food pouch and a few sips of water, and 20 minutes later start saying 'naptime' over and over. She then passes out as soon as I put her in the crib. She is still sneezing a lot today. My question is... why was she awake/active yesterday when she was spiking these fevers but today, when the fevers are gone, she seems totally exhausted and wants only to sleep?
