Formerly conjoined twins are thriving two weeks after separation surgery.
Lasandra Sanatis is splitting her time between daughters Maria and Teresa.
Two weeks ago surgeons separated the 19-month-old girls during a rare and tricky operation.
Last Thursday, Teresa took her first steps.
Nurses are using life-sized doll replicas of the twin girls to help them adjust.
"All their lives they've been used to sleeping next to someone even just someone being in the same room with them they've experienced a lot of separation anxiety they're not able to process yet," says World Pediatric Project's Rocio Watson.
The WPP funded the separation surgery for the girls.
The girls are doing well, but there's still no word yet on when the girls will be able to return home to their native Dominican Republic.
