difficult child is now two weeks into a stay at a diagnostic center. First weekend he had visit with me for 2 hours mostly trying to negotiate getting out of there which I did not agree to, but he did ask in a polite way. He also saw grandparents and stormed out after 1/2 hour when they would not agree that he could live with them. He complained then and throughout the week of no offsite visits. This weekend I saw him - left after a 1/2 hour as he was very sullen, only speaking on monosyllables when he did speak, and obviously not wanting a visit with me. Grandparents did agree to an offsite visit but when they would not take him to my house (as I don't feel he is ready for visits here yet) he would not interact with them but lay down at their house and took a nap. At what point would you stop putting forth the effort to have visits given his nonresponsiveness and/or how long would you keep trying to connect with him? I call him by phone daily but he is monosyllabic and sullen then too.
