How do I navigate this

[GroundSwell]

So I'm a single dad and my daughter stays with me for 84 days in a year, I will be out of the country for 6 weeks or so and the mum is insisting that I pay extra to support our child over the summer holidays (to account for the days I will not be having her)

In response to this I have told her that my parents, 'the grandparents' have offered to, and are more than happy to, accommodate for her care in my absence

The mum is unwilling to do this, short story is my own mother is great with kids but my ex outright dislikes her.

The ex is also threatening to tell the cms if I don't pay her for the missed care, despite me insisting I have made arrangements for her care via the grandparents.

Now;

• as my daughters parent, do I have a right to stipulate how my daughter will be cared for in times where I'm scheduled to have her, but am away?

• if she refuses my request for the grandparents to assume care for 6 weeks, should I still pay her extra?

For note, it's not that I'm reluctant to give her more money, it's more that she already receives a non trivial amount of money from me as a proportion of my income and I strongly feel that it more than covers my daughters care. In addition, it maintains contact between my daughter and her grandparents, which is a win.

Thanks in advance

Do better.

I have no words.
Unbelievable.

How often does she usually stay with her grandparents? You’d think if it’s not pretty regular it would be better for her to be with her mum while you are gone. You both need to do better, your daughter isn’t a transaction to argue over, mum wanting more money to have her own child, dad wanting to wriggle out of paying more money for his own child. Put your daughter first rather than petty disagreements or point scoring with her mum.

As always the first post nails it

I think there has been a misinterpretation here of sorts.

Seeing grandparents forms part of her normal routine because I live with them currently so that's thats that

Further to that I've actually just given ex pro rata difference in cash to cover costs over the summer holidays, this I now see as being fair I suppose as she will be carling for daughter for an additional 10 nights (assuming she won't allow grandparents contact and stay over)

I care not for point scoring, this is a matter of maintaining contact, main issue is ex reluctance to allow daughter to stay over with the grandparents whilst I'm gone. As per bulletpoint one, is there anything I am able to do about this?
