A 2-year-old boy in a stroller was grazed by a school bus yesterday that didn’t stop in time at a Brooklyn intersection, witnesses said.

The toddler was taken to Maimonides Medical Center with minor head injuries.

Witnesses said that the mini school bus nicked the child in the head while his mother was crossing the street at 20th Avenue and 62nd Street in Borough Park with another small child.

No criminality was suspected and the bus was not carrying any passengers, cops said.
