They call it is the fruit snack challenge. It doesn't have to be fruit snacks. Moms and Dads everywhere are using anything. Cookies, chocolates, candy etc.
You put a bowl of the goodies in fron of your toddler and simply tell them to NOT eat them until you return. You record them to see if they listen.
Well, Kylie Jenner does it to her cutie baby girl Stormi and watch what happens!
LOVE THIS!
