Lima, Peru ? Peru’s “miracle baby” on Thursday underwent a successful second operation to fully separate her legs and allow her to walk unassisted, according to the lead doctor on the eight-person team performing the surgery.

“We have finished with the final part of the thighs. After recovery from this operation, she probably will be able to walk in better conditions,” Dr. Luis Rubio said.

Milagros Cerron, whose first name means “miracles” in Spanish, was born with a rare congenital defect known as sirenomelia, or “mermaid syndrome,” which left her legs connected from her heels to her groin.
