Dd's bedtime

[GettingScaredNow]

Ok, background
Split from abusive h in July, issues over contact ever since for various reasons. I do not restrict contact but he does not want it during reasonable hours.

His latest thing is to attack dd's bedtime . She is 4. I have her in bed for 7. She just started school, and is visibly tired and for a child that used to fuss and fight a bedtime we now have problem free bedtimes as she is shattered.
He is saying that her bedtime is earlier then needed and I have done this intentionally so he can't see her midweek.

I've offered him to take her after school and bring her back at 6 (6.30 latest) fed, or 5.30 if I'm feeding her.

Extra info: he finishes work at 2. Is home by 3. Lives 5 mins away. Wants to take her out after dinner cos he wants to rest/nap after work and pick her up at 6 for an hour.
He also has form for poor time keeping (routinely bringing her back 2+ hours late)

Aibu?
Is her bedtime ridiculously early for a 4 yr old?

He can't cope with them both at TW same time. Again, not that he can't keep them safe but he doesn't enjoy it cos he can't play with them both. They have different needs, different abilities. So it's about him, but he spins it, so it sounds like he is thinking of them. And that of corse makes me sound selfish for wanting him to take them both.
What self respecting mother would want to be without her kids??? most of them for an hour or 2

He does think he can convince anyone to see it his way. He refuses to accept that PR means parental RESPONSIBILITY and insists it means parental RIGHTS.
He does seem to think it is right to have one to one time and 'special' time etc cos he doesn't see them often. Where as I should facilitate this at his convenience as I see them all the time....

He's warped. But it's not about the kids. It's about him. I see that now

There might be a valid argument that it's better for the kids to see him separately, I suppose - but absolutely not at a time which suits his naptime rather than their bedtime. Then again, from what you've said your kids like their time together in the afternoon (or at least, the younger does?).

My 4 year old is in bed asleep by 7 - 7.30 so no it's not early IMO.
