One more shot to discuss custody schedule and what to do if ex doesn't agree?

[ILikePizza2025]

I plan to reach out to my ex-wife during the first week of August to discuss the custody schedule for our kids. Be the fifth time trying to start a conversation, once with a legal document. I would like to propose the following arrangement for the time I would have the children with me:

Week 1: Sunday, Monday, Tuesday

Week 2: Monday, Tuesday, Wednesday, Saturday

For logistics:

• Family on my side will drop off our oldest at school every Wednesday during Week 1, while I will take our youngest to my ex's on Tuesday nights.
• In Week 2, family will drop off our oldest at school on Thursday, and I will drop off our youngest at my ex's on Wednesday night.
• My ex will bring the kids to my place by 7 PM on Sunday of Week 2.

For the holidays, I would like to have the kids on the following dates: October 10/31, November 24, 25, 26, 27, December 23, 24, January 1, 2, 3, and 4.

Does that sound reasonable?

Now I know if my ex doesn't agree, then I have to go through the Court. What do I do in the interim if my ex won't let me see my children? It won't be too much of an issue if she doesn't agree, I have family able to watch my children, as it's only every Wednesday I would be working. Any insight or advice?

That would be better for the DCs as well. Not so much changing around.

Yes, Mom is on a 5-2 schedule. Dad is on a 4-3 schedule. With drop off of the youngest on Wednesdays at 8PM. Pick-up for Dad at 6PM on Sundays and Fridays by my family. The Oldest Mom of the children picks them up Thursday after school.

Agree. And it means both parents get a proper weekend with the children and a weekend off. The initial suggestion, ex only got every other Saturday away from the children but had them back again on Sunday. Is that right?

@ILikePizza2025 Children at my DD's primary school were re-enacting Squid Games on the playground, mostly where an older sibling had seen it and one child was told about it, or had seen a trailer/snippet. Then that child told all the other children how to enact it. Doesn't mean they all see it.
In Reception they were playing "Zombie tig" because one of them had seen an older sibling act like a zombie, not because they'd all seen Walking Dead.

Till mid-September, I have every other Sunday, not Saturday. Didn't want to risk the change of schedule with my oldest starting school and my ex not handing the children off, and I would miss a day with my children.
