Personally the thing with the phone is just plain out wrong. I think that you should try to get some one on one time with your sister. If your calling to talk to your son, and she won't let you talk to him that is just wrong. It sounds like your only seeing him because it's court ordered. I don't know if you live in the states. If you do, I would get a lawyer, or a different lawyer. I'm not saying you just take him from her, because that will hurt him. There just needs to be something going on where he can feel safe with you. Unfortunately all this battleing hurts the child. I would try talking to your sister first, and see if the 2 of you can resolve some of these issues. If not your going to need to just keep fighting. I wish you the best.
