Cass, when you say taking his willy out and wetting the bed... do you mean what I think you mean??? As in a deliberate act?? If that is the case it sounds like there could be some wanting attention which would sound very normal if he's just come into your care. He may... or both may need some expert counselling with a child counsellor to help them with the upheaval lately - coming to live with you guys from what wasn't too stable for them so they're adjusting. Just a thought that may help.

Hope there's something to help you hun.
