Thanks for your advice, La Mariposa. Luckily, I've managed to find a lovely nursery that are allowing me some flexibility regarding the days I will need. I've just provisionally booked the days that Grandma can't cover! I'm obviously fortunate that my request 'seems' to have been accepted, but I can't relax until I know its definite! Hurray, don't they need a very good reason not to offer you PT? I hope you got one. 0.7 doesn't seem like a reasonable solution at all!
