Chelsea Kidz Stop, which sold toys and clothing for the ten-and-under set, closed after more than three years in the Sylvan Building downtown. Heidi and Eric Langenderfer initially opened their shop at Oak Tree Plaza on Old US-12 before making the move to Marj Daniels’ former antique store space. “Our lease was up,” Heidi says, “and it wasn’t worth it to be in that spot anymore.” They continue to operate Little Conductors, their trackless train rental business, out of their house. Kitty & Company–a home and office interior design business–moved into Kidz Stop’s space in November.
