ANN ARBOR, Mich. – Doctors at the University of Michigan have separated 1-year-old conjoined twin sisters. Sarabeth and Amelia Irwin of Petersburg, Michigan, each had their own arms and legs and heart, but their livers were connected, C.S. “I’m a father of twins and know twins are very close,” Mychaliska said. The parents, Alyson and Phil Irwin, learned about the conjoined twins during a pregnancy ultrasound in 2019, four months before the birth by cesarean section. “This has been a giant experiment in the power of positive and the power of prayer," Phil said.
