The twins, separated at Stanford University in a complex and risky procedure, have recovered faster than expected and will go home in a day or two, ahead of schedule, the San Jose Mercury News reported Tuesday.
Joined from navel to breastbone, the twins had fused livers, separated in the surgery and now working autonomously, doctors said.
About one in 200,000 live births is a set of conjoined twins.
Just one week after the Nov. 1 surgery the twins were out of intensive care and moved to a regular hospital room.
Angelica and Angelina have physical therapy and occupational therapy daily to build their strength, endurance, gross and fine-motor skills and will continue to make visits to Stanford for medical checkups, doctors said.
