Sylvia bonds well with Maxwell's children and visits the Sheffield home (and eats their food) frequently. After becoming the step-grandmother to Maxwell's children, she became a grandmother to Fran and Maxwell's children, Jonah Samuel and Eve Catherine. Sylvia also has two granddaughters from Nadine's marriage. Initially when the family was moving to California, Sylvia and Morty were going to stay behind in New York, but in the finale they went to live in California with the Sheffields.
