Having adult children doesn't remove the practical challenges of solo aging if they live hours or a country away — day-to-day support still needs to come from somewhere local.
Separate emotional support from logistical support
Your children can remain your closest emotional connection while a local network (neighbors, friends, professionals) handles the roles that require physical proximity.
Keep them looped in without relying on them for daily needs
Share your local plan with them explicitly — who's local, what documents exist — so they're informed and can step in for bigger decisions without being expected to handle daily logistics from a distance.
Video calls on a regular schedule maintain closeness even when in-person visits are infrequent.
