r/HighConflictCoparents

I have no idea how to address if I even should. My daughter (9) and her step brothers (close to the same age) have complained that their parents (my ex and his wife) are being very loud at night and keeping the kids up. The boys know it’s “adult” activities and it’s been going on a lot apparently. What would you guys do? My coparent hates me and will not coparent with me under any circumstances. My daughter hasn’t had the talk yet but the boys have. How do I handle this with my daughter?

My daughter is kindergarten age. Before all this, she slept independently in her own bed without issue.
When her mom and I first separated, we actually tried to be cooperative. We finished our lease cohabitating in the same house with separate rooms because we thought it would make the transition easier on our daughter. It did not go that way.
Quickly, things got tense, and her mom regressed her into cosleeping with her (mostly because she thought it was hilarious denying me a goodnight routine with my daughter while I’m down the hall talking to a locked door).
Now after a long period of my daughter sleeping with her mom regularly, we’ve started a true 7-on/7-off schedule, I’m in a new house, and my daughter absolutely cannot handle sleeping alone in her room at my house.
She cries, says she misses mom, misses her dad, asks to leave, gets out of bed over and over, and seems genuinely distressed, too anxious to sleep.
What makes this harder is that there’s now a new boyfriend in the picture, my daughter is aware he may be moving in, and from what she’s told me, she’s already been sleeping in the same bed with this guy and her mom. She believes this is the perpetual plan. Her mom has told her (and me) that she plans on cosleeping indefinitely.
I do NOT want to traumatize my kid. But where the fuck do I start. 

Hi all. The other parent frequently demands I supply items for their parenting time with child (Currently they have limited parenting time to public places due to DV). Historically this has been car seats, strollers, etc. I have provided these everytime as I want the chid to have a great experience with both parents. However these items come back broken or intentionally dirty (they will encourage child to jump in mud with shoes I’ve sent child in). Lately the request has been child’s new bike I purchased. Other parent doesn’t pay court order child support and has not financially supported our child so in case the bike comes back broken, they would most likely not pay to replace or fix. I’m already mentally preparing for the emotional and verbal abuse I’ll endure. Is there any advice on how I can tell them I won’t be providing these child’s bike to them?
