The question as far as how to talk to mom and dad can be one of the most difficult and daunting tasks especially whenever the children live out of state and they are not quite sure how their parents are doing. But when they come down, they realize that they may require a higher level of care than what they’re able to receive at home. It is very, very difficult to have that conversation.
So I highly recommend that you start off slow with asking, “Well, have you considered?” Maybe even from a standpoint asking for more help. But I would never go in full strong saying, “We need to move,” because that is never good for anyone.
