Explain how you would use your understanding of one of the major developmental theories to deal with each of the difficulties listed below:
1). Your infant daughter puts everything in her mouth, including the dog's food.
2). Your eight-year-old son is failing math; all he cares about is baseball.
3). Your two-year old daughter refuses to wear clothes you pick for her every morning, which makes getting dressed a twenty-minute battle.
4). Your sixty-eight-year old neighbor is chronically depressed and feels she has wasted her life.
