Yoko says to Juanita that she herself didn't want her mother to leave her side on the first day of school. This never appeared on the show. Instead this is a reference to the book called Mama, Don't Go, the first book in the "Yoko and Friends" series. Many of the books in this series feature stories seen on Timothy Goes to School, though this particular book features events similar to those in the first half of this episode but involving Yoko instead of Juanita. Juanita instead first appears in the "Yoko and Friends" book titled Make New Friends.
