What does Tasha represent

Tasha, the doll, symbolizes Sylvie’s deep, everlasting love for Grandma. Grandma made Tasha by hand and gave it to Sylvie when Sylvie was a young child. Sylvie loved the doll but misplaced it before moving to New York. When Sylvie returns as an adult to visit Grandma, Grandma finds the doll and lovingly gives it back to Sylvie.
