Bring it up to your T.

My T has yawned. When it happened several sessions in a row, I brought it up to her. I told her it made me concerned she was too tired. It made me wonder if she was hearing what I was saying. I wondered if I was not talking about core issues..boring her? She hadn't realized she was yawning and apologized.

The obvious clock watching and googling seem to me to be amateurish mistakes. I would figure out what these mean to me and tell your T.
