Doting dad Burtka took to Instagram today to share a too cute Instagram of 6-year-old Harper and Gideon, and we can't believe how big they're getting. In the snap, the little tykes are shown whipping up a batch of Stone Soup at school with their chef father, and from the looks of it they are already pros in the kitchen. "Look what we made in school today! #stonesoup #sharing," Burtka captioned the 'gram of the trio showing off their creation. The recipe comes from the 1947 classic book by Marcia Brown of the same name, which is based on an old French tale that tells the story of three hungry soldiers who outwit the greedy inhabitants of a village into providing them with a feast.
