@Mark3101 Your situation doesn't meet the criteria for Extenuating Circumstances, so cancelling those bookings would basically mean murdering your listing's desirability and putting an end to what is currently an excellent reputation as a host. This is not a good plan if you have any intention of doing Airbnb again in the future.
However, if your daughter is able to assist you with honoring those existing bookings so that you stay on the up and up, you have a way forward. You can block the remainder of the unbooked dates and pause the listing, there's no penalty for that.
