Switched at Birth Casts Meredith Baxter as Daphne’s Grandmother

The Switched at Birth family is about to gain a new member! And no, no one is pregnant ... yet.

Family Ties’ Meredith Baxter will play Bonnie Tamblyn Dixon, Kathryn’s mom and Daphne’s biological grandma. Bonnie’s rolling into town for a quick visit next season, and she’s bringing a suitcase full of drama with her.

Expect tensions to be high with this matriarch hanging around!

Be sure to catch Switched at Birth when it returns to ABC Family on Tuesday, January 3 at 8 p.m. ET.
