I'm not 100% certain but I think LGR had his first sleepwalk last night. At about 22:00 we heard him start yelling out "Mummy, Mummy." He sounded a bit worried but not scared, not agitated. I wandered out of the adults bedroom to find him standing at the top of the stares apparently thinking Mummy was downstairs watching TV.
I'm a bit vague on what was said by me (I probably told him Mummy was asleep); but LGR said nothing. I took his hand and walked him back into his room and without a single word he climbed back into bed. No conversation, no requests. Nothing. As soon as his head touched the pillow he was straight into his sleep breathing rhythm.
LGR can't remember a thing about it.
