Can I say no to this

[regal23]

So my ex and I have been separated 3.5 years .
He has been collecting dc Tues,wed,Thurs after work around 5pm and dropping back to me at 8am the following mornings. He takes him every Saturday 9am-5pm and every second Saturday 9am-12pm Sunday. He has sent me a message proposing he takes dc as usual Tues-Thurs but dropping him to school instead of back to me and then Saturday 9am-3pm and second Saturday 9am- 9am Sunday can I say no to this? If it goes to court will a court give him this ?

If his dad isn’t your problem your other kids aren’t his problem. He’s being reasonable.

Why doesn’t he pay maintenance? Is it because of the overnights? They are pretty minimal but surely it’s better for you if he drops them to school?

I don’t understand what the problem is.
