Urinating & Deficating in Bedroom

the three things a parent CAN"T and SHOULDN"T control. That said, we too had children who used bathroom functions as a way to control (due to previous abuse and control issues) and they are now fully healed. It took time, I am not sure there is any "magic cure" (and believe me, I have had many days I wished there were!!) As time has progressed with ours, bathroom issues have decreased also. All the above tips, (especially white vinegar and water!) are really great. That and time, time, time and more time.
