Is DSDs mum being unreasonable?

[TheNightIsDark]

Background- had residency of DSD from 6 months to 2.6. DP had a breakdown, DSD went to live with her DM.

Last year DSDs DM moved 100 miles away to live with new partner. She did half the travelling (EOW access, she did one weekend a month) then stopped in December as DP lost his job and couldn't pay maintenance.

Maintenance all back up and running (and backdated). She still is refusing to do half the trips. She's asked DP to swap this weekend due to Mother's Day which he did but asked if he could have DSD half of Easter (including Easter).

She said no as he has her for christmas. She had DSD for her birthday last year (and this due to school sbd distance), Easter and christmas. She refused extra access over half term saying her sister was visiting. Turns out it wasn't true.

We think she's refusing because she doesn't want the CSA amount to change. DP has said repeatedly he would pay whatever as long as he got more time with DSD as now he can't just pop in if it's ok with her DM.

We can't afford court for more access. Mil has offered to pay if it comes to it but we don't want DSD stuck in the middle of arguments etc.

Is it unreasonable to ask for more access? My parents split all holidays so for me it's the norm.
