My DS2 is 10 and over the past few weeks has started sleepwalking. We find him in the kitchen or in the hallway with no idea of what he’s doing. Is he going through some horrible trauma that we don’t know about (I’ve asked and he says he’s fine) or is this normal? Other DS didn’t do this more than once or twice but was much younger. We’ve made sure the house is safe at night with a light left on and nothing left lying about but I’m still worried. Any advice?
