DSC are 7 and 8 and my DD is 7. We have been together since they were all babies so they've grown up together, and we now have two children together, too. The DSC do not get along with each other and are mostly kept separate at their mum's (with one sent to GPs house.) My DD loves them both and would happily play as a threesome or with either one individually. I'm not being blind to my own childs faults when I say she's actually excellent at sharing. The DSC don't have much here because they always insist on taking it home and DD shares all her belongings and doesn't go near DP so they get time with him.
The DSC don't like sharing, which is why they insist on taking things home. During the court process they said to CAFCASS that they don't like coming because of DD. That she won't share, that she doesn't play nicely, that she hogs DP, that he gives her preferential treatment and shouts at them - all completely untrue.
Now DSS is refusing to come if DD is here despite the fact they played together constantly last time, had a sleepover and said they were best friends etc. He told DP in front of his mum that he hates DD because she is so nasty and would rather not see his dad than be forced to see her. DSD and DD get on fantastically well but DSD still has said on the phone this morning that she doesn't want to see DD and asked DP to send her away at the weekend.
When the kids are actually together, it's usually fine and nothing more than the odd standard sibling falling out. But it's getting more and more difficult to get the DSC here because they're refusing to come if DD is here. Increasingly they're being mean to DD either together or separately and its clear that exW is angling for DP to see them alone.
I don't mind DP seeing them alone (though I think it'd be a shame as we usually all get along fine) but he works away Monday-friday so if he saw them alone then DD and our children together actually wouldn't see him for entire weeks at a time. The youngest is breastfed and the toddler has additional needs so sending them with him isn't an option.
I've offered that I take the other dc out but the DSC are refusing to come if DD is here at all. Yet if DP were to take them to his dads (which we've tried) then they spend the time whinging that they miss DD and want to play with her!
Has anyone been in a similar situation? DD has no idea of the things they say about her and doesn't understand about all the changing moods. DP has stood up for DD and told the DSC in front of their mum that they aren't telling the truth. ExW said he's despicable for favouring DD and that she'll fully support them in not seeing him if DD is here.
