Plan the time

Pick a suitable time, when you know you will be able to talk to your loved one in private and without interruptions. Approach your loved one at a time when you know they are usually calm, and try to keep all discussions away from times involving food, as tensions and anxieties are already running high.
Maybe once they have settled down for the night, or just before bed.
Decide if you want to do it alone, or if you would like another family member or friend there for support. However try to keep it small as you don’t want your loved one to feel attacked, or as if everyone is ganging up on them.
