In the wee hours of the morning Little Guy came to my bed. He wanted to snuggle and after a bit he said "Mommy, please get me medicine and the white thermometer".
The fact that he was asking for medicine was a pretty good clue to how unwell he felt. Also, asking for the white thermometer - that is the "real" one - meant he wanted to have his temperature taken and not just play doctor.
Little Guy spent the day on the couch. He slept most of the morning and turned it into a boat in the afternoon/evening. By bedtime he seemed to be getting back to normal.
I don't enjoy having sick kids but it is interesting to see how they handle sickness differently as they get older!
