The toddler's father took her to get medical care, but the teen was unhurt.
Authorities say a coyote lunged at the teen boy shortly before 7 p.m. Sunday in Rye Brook. About an hour later, the 2-year-old girl was attacked near her home about two miles away.
In June, the town of Rye - about 3 miles from Rye Brook - had two coyote attacks within four days.
A 3-year-old girl playing in her backyard was jumped from behind by a coyote, and a 6-year-old girl was mauled by two coyotes.
After those attacks, authorities in Rye urged parents to keep their kids inside on summer evenings.
Rye Brook is about 30 miles northeast of Manhattan.
