1) Give the gift of companionship
If you live locally, make a visit your gift. If your loved one can go out, take them on a short field trip. If not, bring an old movie on DVD, and watch it together.
2) Provide books on tapeYou can buy one of your loved one's favorite books on tape or CD to provide hours of audio entertainment. Or, you can provide comfort with the sound of your voice. Record yourself reading a book you know they'd enjoy, and send to them, in manageable increments.
3) Help relive a memoryFrame a photo from an important milestone in your loved one's life, and ask them to recall their story. Even if you've already know the story, just listening will allow your loved one to feel the joy of the occasion all over again.
Best wishes for a wonderful holiday season!
