State Police say a woman threw her child after a fight with her mother Tuesday.
They say Diamond Wallace, 23 of Schenectady, got into a verbal argument with her mother on Route 5 in Amsterdam.
Troopers came across the fight and when interviewing Wallace, she became more upset.
She was allegedly holding her 6-month-old child in a car seat, and threw it along with the baby, across the car at the trooper.
Wallace was charged with endangering the welfare of a child and for disorderly conduct.
The infant was left in the care of a grandparent.
She is scheduled to appear in Town of Amsterdam Court February 6.
