Mealtime is often a highlight of the day but can be stressful too. Share the solutions you've found that work! And don't be afraid to ask questions as someone else is probably encountering the same situation.
Tip: try to find out the reasons why a person may not be eating to help gain solutions. (i.e. is there too much food, distracted by noise, was a farmer's wife and always ate in the kitchen, etc.)
