A toddler is in critical condition after plummeting three stories from the window of a Frankford home.

Police said the child, a 3-year-old boy, was inside the third-floor rear apartment of a home on the 1600 block of Foulkrod Street when around 6 p.m. he fell out of a window and onto the sidewalk below.

Medics rushed him to St. Christopher's Hospital for Children, where he is in critical condition.

There is not yet word on what led to the fall.
