To visit his great-grandmother, Greg and Jen find a solution to their sleeping woes, and Matt takes over for Tim as Sophia's soccer coach.

When John starts feeling old, he attempts to make himself look younger, much to the dismay of his family. Also, Heather worries that Sophia's piano recital will be a disaster; Jen, Greg and Lark go to an over-the-top birthday party full of overachieving parents who make them panic about getting Lark into a good preschool; and Matt meets Colleen's mother, Mia (Mercedes Ruehl), for the first time.
