PLEASANTON  (AP) — Two sisters accused of endangering the lives of infants at their Northern California daycare center by binding them too tightly in swaddling blankets have been ordered to stand trial.

Lida and Nazila Sharaf were ordered Friday to face trial on three felony and four misdemeanor counts of child abuse.

Their daycare in Livermore was shut down following an investigation last March.

The city’s police Det. Cindy Moore said in court that at least three babies were wrapped so tightly they were sweating and some had long blankets covering them from head to toe. She said one was “wrapped like a mummy.”

The sisters’ defense lawyer said swaddling and using restraints were common practices to keep babies from kicking blankets off or scratching themselves.
