The Holland Sentinel says police located the 20-year-old woman in Ottawa County's Allendale Township, about 15 miles west of Grand Rapids. The woman had been caring for the 2-year-old girl, who's now in the custody of her mother in nearby Kent County.
Ottawa County sheriff's Lt. Mark Bennett says police received calls about the Internet posting Monday from as far away as California.
Bennett says one bidder who thought it was a hoax called police when the bid was accepted and helped lead them to the woman.
Bennett says it's unlikely the woman planned to sell the child, but instead was seeking money. He says an investigation is under way.
