confusing problem with my teen son

[noname169]

My 14 year old son has been urinating in cans and bottles and storing them in his room, his dad found out and approached him and he said he had no answer but would stop, we just found some more containers, that were probably left from previous ones.
He seems well  adjusted in family and school, has friends, the only change I know of is his 2 older brothers moved away and elderly grandparents moved in, they all 3 now share a bathroom. Has anyone else had this to deal with or any suggestions as to why this would be happening?

I had a boarder who also had the same problem.  Turns out he was very uncomfortable with sharing the washroom with other people.  Could possibly be an embarassing situation for your boy, and he might feel he's going to offend his grandparents, and doesn't want to say anything.  Another incident that comes to mind, is that through the night some people are shy, and the thought of coming out of the washroom in underwear or pj's through the night could be embarrasing.  It's a new situation for him.  Possibly once he gets comfortable with his grandparents, and knows they will respect his privacy, the problem will diminish.

Is he able to get to the restroom when he needs to?  Don't accept that he doesn't know why at this point.  You have to be very empathetic when talking to him, and ask  what he is thinking about that makes him do this.  Tell him it's okay that he won't be in any trouble, just ask "why do you choose this instead of the bathroom."  Ask him if sharing the bathroom with his grandparents is bothering him, and if so it's okay, we''ll work something out. If he still insists that he doesn't know why then I would have him see a professional about this, he may be really mising his brothers and his anxiety is taking this route.  I'm just guessing, but if he stops and you see no other odd behavior it may be okay.  But I would be very vigilant with his actions, so you can stop something before it gets worse.
