The father of a 3-year-old boy who died when day care workers allegedly ignored the child’s dairy allergy and fed him a grilled cheese sandwich is now suing the Harlem facility for $10 million.

Thomas Silvera says in the new Manhattan Supreme Court suit that he gave specific instructions to employees of the now-shuttered Seventh Avenue Center for Family Services about his son Elijah’s food allergy.

But they still fed the tot the sandwich, which led to a severe allergic reaction and his tragic death in November, the suit says.

The pre-K workers didn’t call 911 or use an EpiPen, the suit says. Instead, they called the child’s mother.

Reps for the nonprofit that ran Seventh Avenue did not immediately return a message seeking comment.
