I wonder if he has an ear infection. I had a little who suddenly started walking sideways and it turned out to be an ear infection, she never cried or anything but that was wierd. Also, pneumonia is contagious (I didn't know this till my mom gave it to dd in the middle of summer just by giving her a kiss on the cheek and the dr told me) sounds to me that you need to tell them that he needs to be seen by a dr and you need a dr's note.
