Bad Stewie.
Well I will also admit that until about a year ago Bailey would go in the bedroom in the middle of the night.. sometimes I would hear him jump down and I'd get up and take him right out..but sometimes ..evidentally I didn't hear him.
Our turning point was one night he jumped down and I reacted a little slow and I got up and flipped the light on and he was
BUSTED RIGHT IN THE ACT he was like this

and I was

he jumped on the bed and and I just kept saying (as I cleaned it up) NO! NO POTTY INSIDE.. BAD BOY.. Bailey goes OUTSIDE TO POTTY! and it has NEVER HAPPENED AGAIN.. now when I'm slow to react to his jumping down he whines LOUDER and LOUDER until I hear him..no more just going.
So the moral to my story is.. I really believe in the catching them in the act so they know what it is they have done wrong.. Like ..OOOO she's mad and raising her voice cause I did
that..OOO in the house..OOO I get it.
I have no idea if that's true but I'm telling you it worked for us.
Good luck.
If Bailey can get it so can Stewart!
