The young boy wasn't hospitalized at the father's wishes after members of the Ridgewood Ambulance Corps checked him out following the incident on Prospect Street early Friday afternoon, Feb. 18.
The adult sitter's leg had fallen through the floor, responders said. She was taken to The Valley Hospital.
Hardwood floors in the home were being replaced when the mishap occurred, Village Building Department Director Anthony Merlino said.
"A piece of subfloor weakened by a knot in the wood gave out when [the babysitter] stepped on it," Merlino said.
Permits for the work weren't required, he said.
Ridgewood police also responded.
