We've had a number of incidents in the last couple months where DS gets up through the night because he has to go pee and then he pees some place other than the toilet. A couple times he's peed on the bathroom floor, and a couple times he's peed in front of the bathroom door. Last night he peed right in the middle of the hallway. I heard him get up and went out there while he was peeing. I don't think he knew where he was. I cleaned him up and put clean under wear on him and that whole time I'm not sure that he was aware at all, and then he climbed back into bed. Could he be doing this without waking? Anyone had anything like this happen before? He's always been a good sleeper. We've never had any issues like this before.
