Start with the “bottom” of the sandwich: your children. What’s appropriate to share with them depends on their age. However, by high school, you should be talking about their post-graduation plans and how much you can offer for college or other financial needs.
The “top” half of the sandwich can be more challenging. Depending on their health status, finances and other factors, your parents may not welcome your involvement in their decision-making. They might minimize or dismiss your concerns and be highly resistant. Initiate a frank family meeting with your parents, siblings and their spouses, if appropriate. Many issues can be sensitive, and emotions may run high, so be prepared. One session may not be enough to accomplish your objectives.
