My sister and I are babysitting a 19 month old. Whenever we don't give him what he wants (it either involves junk food, milk, or opening certain things such as a drawer or a cabinet) or at a random moment, he starts to fake-cry and scream! And he'll usually continue to cry until we let him have his way or until about 10 minutes from when he started. The main problem is that his parents let him have what he wants. Any ideas?
