Hi, you now what ,I heard very sad news about the little girl who accidentally choked herself .Her mother left her in the carseat in the car with her brother , her brother was six years old. He opened the carseat the little girl watched out of window , by accident she touched the window knob the window glass came up and suddenly choked the little girl. Somebody saw her and called 911. He also freed her from window,but he left her there. When the mother of the little girl came back to the car, she didn't know about the situation and just drove home. I think this was just an accident and nobody is at fault. In the future, mothers should think about this situation and not leave her children in the car alone.
