As a caring woman you will need to learn to modify expectations, accommodate changes, and set boundaries to avoid caregiver burnout.  Setting boundaries in the context of caring for your parent means setting boundaries on yourself.  Doing this in a healthy way involves balancing love and generosity with self-preservation and knowing what you are offering is good enough.

Setting boundaries is not an act of selfishness, but one of caring for your parent, as well as for yourself and other members of your family.  Setting boundaries entails your recognizing and accepting what you realistically can and cannot do and then communicating this to your older parent in an empathetic and sensitive manner.

A few tips: More tips can be found in my book, Caring Women: The Good Daughter Syndrome  

1. Respect the dignity of your aging parent(s) when responding to their requests.
2. Agree to provide only those services you can manage gracefully and with good humor.
3. Let your parent(s) know that you care, even though you may not always meet all of their requests.
