As you already realize, you are so blessed for your mom to have such wonderful care.
Maybe you could give them a card with a promise of delicious homemade goods after the first of the year, but I am thinking that a long term health facility like your mom is in, wouldn't have Reps. sending a lot of food, like a physicians office would.
You are very sweet to remember your mom's caretakers like this.
You may have had a lot of unfair things happen, but when you look back over your life, remember something good that has happened for you. Replay the good memories. Joel Osteen
