Thanks everyone
I think we are going to get rid of it to be honest, and keep our normal 2 trays in the utility cupboard - we were thinking if we ever had a baby the tray would go as the spare room would be a nursery
There is no chance of them going outside for toileting as they are indoor kit kats
The history behind it is, when we first got Jess we had 2 trays one in the spare bedroom (the tray I am talking about) and one in the utility cupboard, the upstairs tray was never used it so we took it away and he just had the one in the utility cupboard. Then when Milo arrived and they were separated at night to begin with we put it back and then took it away once the boys were spending nights together. Then the behaviourist suggested putting it back in case Jess prefers it because its quite private.
But Jess has never used this tray but I just get worried about upsetting him (yes I am mad) but I guess if he has never used it then he won't be bothered. He prefers the open tray downstairs, and I've kept a really old bed in the lounge because when he had his cystitis problems he used to wee in this bed to show me things were wrong.
