Question regarding termination of daycare contract

[apples and bananas]

I think it's ridiculous that a provider would ask for a weeks vacay when it's not in the contract as accrued vacation.

She has 6 weeks notice, if she replaces the client before she takes vacay in august then that client will be responsible to pay for her week off. Wouldn't she be paid double if she got it from this client as well?

Seems sneaky to me. But I understand we don't have the providers side of the story.

If I were you (the client) I would just lay low until the last payment. Pay for your time until the end and thank her for her service. You don't want to run into trouble in the last few weeks of care.
