I presume shes your daughter- maybe at the crux of it is that SHE wants your attention now as well, and does not know how else to get it but by demanding she comes too?I am a bit worried/mystified about her comment "because you're mine!" to the child, but it depends i guess, on if she has 'possessive' tendencies/thoughts,or if she's always felt unwanted by you, -or if any of that was one of reasons he was placed with you- any mental health reasons on her part i mean?- you could go back to court over the court order- or contact where they issued it i suppose? But that might make it worse- how about making it ONE night once a month- then telling her in no uncertain terms that THIS is your GS's visit- that you need to use it to give his time to you, and vice versa- as she has his time& attention ALL the rest of the month- POINT THAT OUT TO HER- as frankly, up to now you have not done? No more pussy- footing around her, tell her straight.Then when he's in bed, give HER some of YOUR attention too, as HER parents?! Ask how she really is, how she's coping, managing etc, if she gets out & about, has time for herself, etc etc, or just wait on her a bit, cook a meal for you all, that kind of thing- like you care about HER as not just a means to have her child to see you? Maybe that's what she wants/needs but can't ask for it?Try it and see.If not, you have no option left but go back to court & get them to lay down in law EXACTLY what she needs to do to comply with that order- if she's to LEAVE child alone,without her, at your home, then so be it.She must then comply with it.But try the 'be nice to her too' method first.You might get to enjoy time with her in the end.?
