My children see me use sharp knives in the kitchen every day. When I can safely supervise children using a sharp knife, I allow them to do so. In fact, making homemade applesauce is a family event.
But what about the 3-year-old? Is she too young to use a knife?
No. I have taught Little Sister to use a knife. By slicing her own banana with a butter knife, she learned how to use the knife.
But that was a butter knife. What about a sharp knife?
