Episode titles are named after art pieces.
Many of the actors who played hearing characters in the show did not know American Sign Language before receiving the part.
When the series began, Bay (Vanessa Marano) and Daphne (Katie Leclerc) were both supposed to be 15 (consequent to the show's premise, the characters share the same birthday). In reality Marano was 18 and Leclerc was 24, but their birthdays are less than a week apart.
The names Bay and Daphne are interchangeable - Bay is the type of tree that the mythological Daphne turned into while she was being chased by the God Apollo. Both are consequently common names for laurel.
Vanessa Marano (Bay Kennish) has a sister named Laura Marano who is also an actress. Laura has never acted in Switched at Birth, but when Vanessa was asked to bring in photos of herself for the set, she brought in photos of both her and her sister. In season 3 episode 17 - "Girl With Death Mask (She Plays Alone)" - Bay visits her cousin, and he shows her a picture of her deceased, biological aunt. Laura is the aunt in the picture.
