Milagros Cerron, whose first name means "miracles" in Spanish, was born on with a rare defect called Mermaid syndrome, or sirenomelia, which is often deadly.
She is thought to be one of just three survivors of the disorder in the world.
Doctors said - Normally babies like her die within 72 hours of birth.
Before her four-hour operation, Milagros' legs were trapped in a sack of tissue and fat down to her heels. Her feet were splayed in a "V" that looked like a mermaid's tail.
After the operation - Milagros is seen walking on his first day at kindergarden.
thanks God, she finally can walk after the surgery
