We're still having similar problems, however.......

Watch closely when she cries during sleep. Once or twice I noticed DSs eyes were actually closed when he was crying. I think he was crying in his sleep or having a nightmare. Often I was waking him up barging into the room to comfort him or picking him up. So if his eyes were closed, I gently pinned his arms down and quietly shhhhhed.

No Cry Sleep Solution also mentions this, and I read it once I think on BB. He was about the same age when he was doing it.
