AIBU to not like this sleeping arrangement?

[Gillacuddy1]

Had a court order put in place where dd (4) will spend a night (every other weekend - goes up to whole weekend at end of month) with her father.
My relationship with ex is strained (to say the least - hence court order) and have never seen eye to eye with the mum.
Arrangements are that my dd stays at x mils one bedroom flat (which is not much bigger than a studio apartment and dd in bed with Nan) and ex stays there too on a blow up bed/ sofa in the front room.
What wasn't mentioned in the order is that Nan has new boyfriend who lives with her and the last time dd stayed there she shared a bed with Nan and nans boyfriend whilst dad and dad gf slept in the front room.

AIBU to think this is not a suitable arrangement?

YANBU

YANBU at all. Sharing with her Nan, fine. Sharing with the boyfriend, absolutely not fine. Can they not at least get her a blow up bed of her own?

Why did you not mention new bf? If he wasn't on the scene when the order was, you need to let someone know that the circumstances have now changed. You should have done this as soon as you found out.

Fuck no. Absolutely unacceptable.

Nan was already with said partner and it was stated he wouldn't be there at weekends and if he was he would sleep on the sofa. I sent Nan a message about this weekend and the sleeping arrangements and it got totally ignored 😩

This is totally unacceptable, and I am highly suspicious of any grown man who thinks it's ok to share a bed with his girlfriend's granddaughter.

Well now you do know have you got back in touch with anyone to let them know the sleeping arrangements and that you're not happy?
