Worn Out?

Caleb woke up last night at 11pm complaining of his teeth & head hurting. We checked him for fever (none), gave him some tylenol for the pain and put him back to bed. At 3am, he was back in our room still in pain. Had a low-grade temp of 100.4 for about an hour then it started dropping on its own. We gave him some stronger pain medicine (codeine) and let him sleep in our bed until 4:30am when it was time for his regular meds. He slept until time to leave for radiation & fell back asleep in the truck on the way there. When finished with treatment, he didn't eat his usual amount of food for breakfast. When he got home, he didn't want to eat (unusual) and asked to go to sleep. He's been asleep since. It's now 2pm & he's still sleeping.  I guess all the activity over the past couple of days has just worn that little man out.
