Should I refuse to let ex take the dc

He has agreed that he should get the dc about 30% of the summer holidays as I'm a teacher. He will probably deny remembering this agreement.

We have agreed nothing for the holidays as I find saying nothing gets me more time with the dc. He was meant to have them today till Saturday am but when I dropped off he said his gig had been changed to Friday night so can I have them Friday and he will have again Saturday.

I agreed- was on the fucking doorstep, but now I want to say no to him having them back on Saturday. I don't want half a day here and half a day there as they need to readjust when back from his and it restricts outings etc. I also resent having to fit in with his sodding gigs.

Would I be wrong to refuse and say he'll have to wait till Wednesday?

Some parents and more importantly children can cope with flexible access and some can't. But this sounds more like him not being organised - is this is hobby or his living? If a hobby I especially would not go out of my way to change my arrangements; if it's the nature of his job/genuinely can't be helped then I'd be minded to be more flexible.

If he's cutting his time shorter then that's his choice. You are not his baby sitter and certainly do not have to chance your days about to fit around his last minute plans

You agreed. Stick with it this time but have a conversation re future plans.
