ABC Family has given a back-order pick-up for more episodes of the dance dramedy "Bunheads," the network said Friday, also announcing that it had picked up "Melissa & Joey" for a third season, and "Baby Daddy" and "Switched at Birth" for those series' second seasons.

The renewals and pick-ups join an already announced reunion special of "Beverly Hills Nannies," which will air Sept. 4 on the ABC Family.

"Bunheads" and "Switched at Birth" will return this winder, while "Melissa & Joey" and "Baby Daddy" will return in spring 2013.

ABC Family president Michael Riley touted the re-ups as evidence of the strength of the network's lineup.

“Two years ago we embarked on a bold strategy to grow the breadth and scope of original programming and create a Wednesday night summer comedy destination,” Riley said. “The new series have resonated with our viewers, and the combination of drama, comedy and reality brings great depth to our lineup. Our stable of strong series continues to grow, and I’m thrilled with the strength of our schedule.”

"Bunheads," which premiered in June, stars Sutton Foster as Michelle Simms, a Las Vegas showgirl who impulsively marries a man and moves to a small coastal California town, where she uneasily takes part in her mother-in-law's dance school.
