Fever... or not?

OK... when Landon went to bed the other night he had a very high temperature. I was sure we would be calling the doctor first thing the next morning. I checked on him throughout the night and he still felt very warm. So, I was ready for the worst when he woke up. Surpise - he was fine and barely had a temp at all!!! He was bright eyed, bushy tailed and ready to play! I just don't get it. I was thinking to myself, "he wanted Mommy to stay home with him today, didn't he???" Then another surprise, later in the day his fever shot up again, although not too much. Anyway, he is fine now and we avoided a trip to the doctor's office but I sure would like to know what was causing it. My guess, fluid in the ear. It is so bizarre but just shows how resilient kids can be. I'm just happy that he is feeling better!
