Yes kids often adjust to reduced diopters really quickly.
Important to note that a safe margin for changes is 3-4 months. Admittedly we have far less data for children than adults, so this is all derived from the latter. Seems biology really takes about that long to fully adapt.
So, no rush with changes. You may even just stick with the current setup of one focal plane for a bit and see how it goes.
Other than that, possibly just a cylinder reduction for next close-up may be worth trying. Could be easier to assimilate and since she will tend to forget to change them, perhaps more easily adjust to less of that correction.
Again though, no rush.
