If she is that concerned I would be worried that on the in between weeks there won't be any money for me so I would probably accept the two weeks pay at a time but make it in advance. Right now I have some that pay for two weeks but they pay for this week and next week so I cash the whole check now so on the nonpay weeks for the parents I already have my money. Only bookkeeping thing I need to do is mark paid for the following week when I enter the money.
