Although I also agree with Royale, it sounds like in your case, the other party was probably under some kind of pressure to settle the matter, either financial or from her legal counsel who recognised that her case was not strong.
I had mixed success with mediation. At least you got to attend mediation in person. Mine was originally booked for mediation at the Vic Bar Mediation Centre last year but had to be cancelled due to Covid restrictions and we held it over Zoom (which actually saved us money as the fee for the rooms were substantial on top of the cost of representation and the mediator!
In the end it worked out for me and we settled due to a really good mediating barrister, but I think ultimately it came down to the fact that the next step was going to be a trial and neither of us wanted it, although I had more to gain from a trial than she did, so I was prepared to go there if necessary, and I think that applying pressure on an unreasonable party is what eventually gets you the result. Earlier on in the legal process, the unreasonable party (especially if they are the primary carer) tends to feel like they can do what they want with no consequences, and sadly that's largely true.
