For John Naum, going to work with his dad as a child meant testing the candy made in the Sweetland Candies shop. He’s now got grandchildren doing the same thing. Chris Naum started Sweetland in 1919, the original shop in the thumb area of the state. The shop then moved to Lowell, then downtown Grand Rapids, Burton Heights and, finally, Plainfield Avenue in the Cheshire neighborhood in the 1930s. The family closed that location decades later.
