Every family is different and everyone is going to have their way of approaching uncomfortable conversations. Here a 5 things to remember when having this discussion.
1. Do not wait for a crisis to occur to have the talk. By then it may be too late
2. Do not try to tackle everything at once. Do it over multiple conversations
3. Get the support of other family members or a professional if necessary
4. Ask open ended questions
5. Be factual. Do your research before you have the conversation.
Of course these tips can be used for other conversations such as living wills, trusts, home care, 5 wishes, etc.
