Life in the United States is changing.Twenty-five years ago the housewife cleaned，cooked and cared for the children.The father earned the money for the family.He was usually out working all day.He came home tired in the evening and so did not see the children very much，except on weekends.
These days，however，many women work outside the home.They can’t be at home with the children all day.They，too，come home tired in the evening.They don’t have time to do the housework.
Today she can get help.Mothers can leave their children at the day-care centers during the day.The company a woman works for may allow her to work part-time.In that way，she can earn some money，but she can also be with her children part of every day.
Now many men share the housework with their wives.The husband may also spend more time at home with the children.
In the United States more and more men are becoming househusbands every year.These changes in the home mean changes in the family.Fathers can be closer to their children because they are at home more.Fathers and children can understand each other better.Husbands and wives may also find changes in their marriage.They，too，may have better understanding of each other.
