If you have space on the other day, I would do it. I would have her sign a new contract and only be responsible fore 3x a week...1 day isn't that big a deal to potentially lose a client over...I just had the opposite happen. My favorite family who has been with me since the beginning want to start slowly transitioning from pt to ft. Im really pleased, and as a good will gesture I have allowed them to only pay my drop in rate when they bring her any additional days.
