Cao 18m down the line. To change it what form is it

[WheresAllTheGoodInTheWorld]

So dp took his ex to court nearly 2 yrs ago. Bit of to'ing and throwing and he got alternate weekends. They said no days during week due to his work and that dd was under 5?
She's now nearly 7, his job is now flexible and close to home and most importantly his dd is begging to come for longer. Cries when goes home etc. Says she never sees mummy and always with grandparents. He wants to now return to request longer.
His ex is let's say very difficult and doesn't even let any flexibility I.e our dds 1st birthday. Dsd wanted to come for a couple of hours to give her gift and her mum refused. We then said what about an hour if she started the best d time for her She said, no the court order doesn't state that!
Holidays were meant to be agreed bewteen them. She then 2 days before was saying you can have her this week. Knowing it was too late to book time off. He had to return to court to get them to stipulate the exact times and dates. Which is a waste of their time

Does he have to fill in another c100 form. And start again?

Yes, a C100 and yes starting again including mediation.

Yep start again and focus on its what DSD wants and that her Dad should have first refusal to provide childcare!!! That is a typical clause and not an unusual thing in CAO it would mean he has to be offered to have DSD before grandparents or other childcare being used, obviously it's important DSD continues a regular relationship with her GP but not at the cost of Dad not getting a look in.

Itsv down to her mum putting her social life before spending timw with dsd.
She's with the grandparents in 'mummy's time' iyswim.
But as said he's now in a flexible job and I'm Now a sahm so I'm always here if needed if he got stuck at work for any reason.
Won't have to do mediation as she assaulted dp last summer leading to police presence and prosecution. Just unsure what to write on that part of the form?

Randomness, it's interesting you've said that as I asked for first refusal if ex couldn't make it during the final hearing and the judge said no. I think it's a completely reasonable ask but they said it's up to the parent with contact that day to organise childcare as they see fit.

That's annoying but I guess it's down to circumstances, EOW isn't much contact at all though
