Eliza Stanley is an eight year old girl that the Baby Sitters Club helped out one Christmas through an organization called Santa's Helpers. She lives at 40 Tenth Street Apartment A in Freeport, Connecticut.
One Christmas, she writes a letter to Santa asking for a Barbie doll and the book Little House in the Big Woods. She also would like her sixteen year old sister Jennifer to come home for Christmas. Jennifer ran away to live with her aunt and uncle.
The baby-sitters buy her the doll and book along with some kneesocks and a candy cane. Claudia works hard to track down her sister and arrange for a Christmas visit so Eliza's Christmas wish could come true.
