I'm not sure I follow. If you have 10 days of pay in the bank (deposit)...why does it matter if you have to stretch it out over 5 weeks (2 days a week) versus 2 weeks (5 days a week) it still covers 10 days of pay.

You could have it cover the last 2 weeks of full time care then have them pay weekly for the part time care. BUT...this really doesn't change anything as it's 10 days of pay that they prepaid as a deposit versus paying now. The monetary value is the same.
