My daughter who worked for years in Elder Care settings called this afternoon. She said her best ideas were to make sure existing activity/enrichment staff have tablets or other portable devices they can use to help the residents communicate with their loved ones. Also for family members to be aware that staff is stretched to the max and support them however you can, including being patient and kind with them. Great words to keep in mind always when working with caregivers.
She also suggests having children or granchildren make and send stories and artwork. This would also be a way to occupy your out of school children.
And I suggest sending frequent photos (hard copy) of loved ones, including adult family members and pets. Write names and relationships clearly one the front of the pictures to jog memories and help out any staff members who are viewing with your loved one.
