An Antigo woman accidentally gave away her child’s car seat. Police say the woman stopped at the Safety Building on Sunday evening. She put the child’s car seat into what she thought was her grandmother’s car. It was not,it belonged to a stranger. By the time she figured that out, the car was gone, along with the car seat, the appearance of which must have stumped the car’s owner. The woman asked police to call her if anyone turned in a car seat.
