Hi, both my husband and my son both did this, i personally didnt seek help, i just made sure that they were safe while sleep walking, but i do know you must never wake them or talk to them during a walk, just turn them around and walk them back to bed, my son was the worst, he used to just walk into the lounge where we were watching the tv and sit nixt to us for a while then i just used to walk him back, other occasions he used to wee up the wall, in the bin or on the floor, and my husband once put on his dressing gown got his car keys got into the car and even put the ignition keys in until the cold woke him up before i could get to him, so really just be vigalant.
