I know ur post is old but I could’ve written what u did verbatim. He’s 9. Spends lots of time in his room on the XBox. I think he didn’t wanna stop playing to go to the toilet which is literally right across the hall. Folks here are saying it’s a mental or physical problem but I don't know. How’s ur son now and how did this situation pan out?My son did this and it because he didn't want to take the time to go to the bath,
which was right next door to his room because he was busy playing video games.
