Doctors took Maliyah Herrin back to the operating room Monday night to clean her wounds, so she wasn't feeling as well as twin sister Kendra on Tuesday, according to Bonnie Midget, spokeswoman at Primary Children's Medical Center.

Still, she said, the girls are continuing to heal.

Kendra and Maliyah, 4, are the daughters of Jake and Erin Herrin of North Salt Lake. They were born joined at the torso and a team of surgeons separated them during a 26-hour surgery Aug. 7 and 8. During the operation, surgeons divided organs and reconstructed their pelvic rings.

They are still in the intensive care unit. It's not certain when they'll be moved to a regular hospital room, Midget said, but they'll remain in the hospital for several weeks after that.
