Ex letting child sleeping in bed with their new partner

Yeah I wouldn't like it either. I wonder why she didn't find it weird because I wouldn't want someone's kid in bed with me.
Obviously it's the weekend and the kids might have found it fun all having a sleepover, but he should have had the youngest sleep with his sibling.
What I would say though is don't question the 5 year old on what's happening, you can't change anything and it's not fair on the child.

No I agree that's really odd and I'd be fuming.

I can’t understand why any mother would find that acceptable, I would never put my children in that situation. My youngest won’t sleep elsewhere, it’s either next to me or his dad. My eldest was in his room on the top bunk and one of her daughters was on the bottom. I consider this to be a safety concern so sadly that’s the only way I would know about this, I don’t normally though, usually it’s just me asking if him and his brother had a good weekend!

I’m glad i’m not the only one who would feel this way, it’s awful!

Yeah, that’s a no from me and even more so if you haven’t even met her. I wonder if she’d be happy for her children to share a bed with your ex?

So I have exactly the same issue. My 3 year old son will happily fall asleep in his own bed at home (my house) but will at some point in the night end up in my bed. If I wake, I put him back in his bed. My 6 year old daughter tells me they either sleep in dad's bed with dad and his girlfriend or on the couch. Dad doesn't put them to bed. They have a second bedroom that his other older 2 kids stay in every 3rd weekend. (My kids go to his every 2nd weekend) my 6 year old says the older 2 don't want the younger ones in their room. What can I do? My kids' sleep sufferes, and I feel sick about them sharing a bed with their dads girlfriend. From NZ
