Doctors at Primary Children's Medical Center have seen some improvement in Kendra Herrin but continue to watch her closely to see if a partial bowel obstruction corrects itself.

"The girls spent a quiet day today and even played together," said Laura Winder, a hospital spokeswoman, on Sunday.

Kendra and her twin sister Maliyah, 4, were born joined at the abdomen and were separated Aug. 7 and 8. Last week, they left the intensive care unit, but Kendra has developed a partial bowel obstruction from scarring.

Sunday, doctors also gave Maliyah a unit of blood, according to the Web updates provided at by their parents, Jake and Erin Herrin of North Salt Lake. The blog said both girls were feeling pretty good Sunday — well enough to have a small fight over whose turn it was to read a Dora book.
