The conjoint twins Mackenzie and Macy Garrison were born with a triplet sister. They were adopted by the couple Jeff Garrison and Darla Garrison as their biological mother was not able to take care of them. Macy and Mackenzie have developed different personalities and these rare conjoint twins have two separate set of organs but one pelvis. This makes the separation process more complex. But, Dr. James Stein, Head Pediatric Surgeon of the Childrens Hospital, Los Angles is preparing to separate them and started stretching their skins for that. Watch the video to see the twins.
