My Ex lets my 7 year old stay up till 4 am every othere weekend he has her. They dont leave the house, he barely feeds her. She is very picky and he will only offer a couple of things and she ends up being hungry all weekend. When she falls asleep watching a movie he rubs her arm and says wake up your missing the movie.. what the hell is that about??? its bordering on abusive. when i pick her up she looks like a zombie and he chuckles how she was up late. Is he doing it to manipulate me? I am trying to figure out his motive. He does not want divorce. it is not final yet... i don;t know what he is trying to prove here.
Re: ex keeping dd up all night
I would start sending him emails or texts asking him to please be aware of her bedtime and the importance of sleep.
If no other reason than if you end up fighting for custody, you can ensure that he does not have her on a school night. (I am not against sharing custody on a school night, but if your stbx can't provide her with a good sleep schdeule I don't think it is in her best interest).
The thing I learned early on is there is really no way to control what happens at the other house. It sucks big time. I finally just had to let it go. The only way the courts will get involved is if it is abuse and you can prove it. Which from what you said that is not the case here.
Have you talked to him about it? Really in these situations the only thing that will help is trying to get along with him. If you aren't getting along it is near impossible to have any control over what happens with DD at his house. As far as her not eating I would maybe send her with a bag of food/snacks she likes?
I'm sorry he doesn't parent the way you would like to, believe me I get it. But you have to accept that you can't control how he parents on his time. When DD is older and learns that feeling super tired is not fun, she'll start sleeping on her own and telling her dad to leave her be and let her sleep.
I wouldn't be texting and reminding him. It will do no good and only impress on him that it bothers you.
I would however start working him a little and tell him he's going to make his daughter resent him if he continues. Do this of course without DD present.
Good luck with this. He's playing you. Pretend it's not happening (I know, this will be hard) and tell your daughter that she is going to have to demand that he let her sleep. She's old enough to speak her mind. Eventually he too will grow tired of this eventually.
