Info from Licensor: "My 2-and-a-half-year-old son, Karson, was in his room for 20 minutes and, out of nowhere, comes down the hallway, does a practice hit with his bean bag chair in our living room, and then nails his baby sister. She was standing on her step stool minding her business in our kitchen with me standing literally feet away. She only cried for about 20 seconds and then she was fine. I took off after Karson to discipline him and jumped right over my daughter without checking on her."
