Need help with POC please.

How do I write an order on POC for something like daily dressing change that nurses do not have to do daily after some time but the patient or the care giver needs to continue daily on thier own. Nurses are only to monitor the overall progress and teach family to do dressings on their own.

For example, if I write SN for daily dressing change until 07/15/09 and then 3W3, it sounds as if the dressing does not have to be changed daily at all after 07/15/09 even though it needs to be changed daily but not necessarily by the nurse.
Would really appreciate any suggestions??

Thank You very much.
