No notice

Yeah, I wouldn't really be cool with that arrangement. I know some providers can, and will, do last minute. But I prefer to know in advance who I have for the day. I actually require 24 hrs notice for drop-in. I am guessing she is a substitute teacher?
I see a couple options. She can pay for full-time, and then you must be available on any given day. She can pay for a specific number of days in the month, which may or may not be last minute.It sounds like that is the current arrangement? Or, she can take her chances on you having a space available on a day-to-day basis. I am certain she knows exactly what the situation is, and how lucky she is/will be to find someone willing to work on an as needed, on call arrangement. If not, she will soon, when she tries to shop around.
On the other hand; you could always see it as extra income. If it doesn't really interfere with the rest of your daily activities, no harm done.
