We have recently experienced sleepwalking for the first time in BOTH children. It did freak me out a little in terms of safety concerns--we camp, travel, the kids sleep over, etc. Sleepwalking and night terrors are hereditary, and connected to being overtired, but there is also a link to stress and anxiety. If you start to see this in your child, or an uptick, it's worth asking about any issues going on. A recent study found a link between being bullied and sleepwalking.
