Twin 9-month-old boys were seriously injured yesterday in Brooklyn when a livery cab smashed into a parked minivan, jumped the curb and ran into their stroller, police said.

Patricia Mechuca, 21, was pushing her sons, Gustavo and Daniel, on Fourth Avenue near 44th Street in Sunset Park at around 1:15 p.m. when the livery cab lost control, her friend said.

“We were about to leave. I went upstairs and two minutes later, I heard the crash,” said the pal, Ismael Remigio.

Mechuca was visiting from Baltimore with her husband to celebrate the new year with his family.

She, her babies, the driver and three passengers were rushed to Lutheran Hospital. One of the twins was in critical condition with head trauma. The other six were in stable condition.

The cabby, Gregorio Patino, 57, was charged with driving without a license, reckless driving and imprudent speed.
