Ok so I realise I was maybe being selfish wanting DH with us for Xmas, but I only ever meant part of it. I wouldn't want him to not see DSD, that was never the point. It's turning into a real issue now as PIL not happy to have DH DSD over night only for dinner. (Kinda what I wanted in the first place I know...but) Obviously ex has kicked off....why dinner but not the night, what's the difference. She actually has a point for once, but PIL are very paranoid about the virus and it's not for her or DH to make them do what they aren't comfortable with. Anyway ex obviously has plans of Xmas with no kids as others are going to respective father's/grandparents. Have told DH to stand up to her and say she should be allowed here, but WW3 has resumed! She expects me to leave my own home for him to have DSD here, but has backed down about her seeing siblings as DSD wants to see them. Obviously DH said no to that, as I will be here, and now she says DH isn't allowed to have her at all! Yet again saying he's a crap dad etc and saying DSD doesn't want to see him either etc etc
So small progress but not a winning situation, as no way will I be leaving my kids on Christmas. I most certainly would not be leaving my kids at weekends either, and removing myself from my own home to allow DSD to come over. Ex has to accept I exist, and if she was to allow relationship between kids, she has to accept I am the mother to her daughter's siblings who are still very young. I want to propose a plan for contact between the children but it needs to be slow and steady. Not sure letter writing is going to work as DD isn't very good at writing and don't want to make it stressful. I could write for her but then is ex going to kick off because I was involved in writing .... Probably, she's so petty. The thought of this re-introduction makes me very nervous, but it has to start somewhere. However if I'm never allowed to be part of the picture should I bother? Its not right for my kids to be taken from me to see her, and I don't want ex getting her way all the time, she's ruled too much of our lives already. Equally current situation is not right either. I'm hoping if DSD wants to see us all, including me, as DH has told me, then eventually her mother will give in to her? But what if that's another 3 years down the line?! Anyone had experience of introducing, or re-introducing siblings? How did it go? Any dos or don'ts?
I would, in your shoes, start the introductions between the children. I'm not saying leave your home for a weekend, not at all, but there is absolutely no harm in your DH having the three children together for an hour or two without you.
The more a part of your home your DSD is, the more she'll want to to be there, and the more her mother will be under pressure to allow it.

You need to separate your DSD from her mother to an extent. The situation with her mother and your DH is seperate to introducing the children and a balance needs to be found between pushing her Mum and making small steps (especially if your DH is still not willing to go to court)
It should be kept light and airy. Keep the kids busy - harder at the moment I know with restrictions - your DH could take your DSD and your eldest to the park, or all three children to the zoo. Something that isn't just a lot of focus on being sat around talking and 'getting to know each other'.
The ex has backed down on your DSD meeting your children. That shows there is movement in her position. I would put money on that being because your DSD is getting older and more vocal in her wishes.
What is your DH suggesting for Christmas? What about a compromise of Christmas dinner at the GP's and staying over in a Premier Inn (They are surprisingly cheap on Christmas normally as they are quiet)? Then back to Mum on Boxing Day. Then DH can be back home with you and the younger kids?
Your other option is for your DH to bring your DSD to your house after dinner, but that is a lot to deal with in one day - the excitement of Christmas, meeting her siblings and knowing her mother is likely to kick off the next day.
