Question

explain Hitler's ideology regrading women and this policy towards them

Answer 1

Nazis held very traditional views about women and the family. Women were to have a passive role of staying at home and looking after their families, while men were to be the active provider and protector of the home. 
Women were not to take jobs, but instead stay at home. They were to marry only racially pure aryans and have as many children as possible. Young married couples were given incentives. There was a lot of pressure on women to give up smoking and dieting so that they could have more healthy babies. In fact, the birth rate did rise, although not by the large percentage the Nazis were expecting. Women were given awards and distinguished places at meetings if they had 4 children and above. 
However, when the war created labour shortages in key industries, the government found themselves in need of factory workers. Women refused to abandon their traditional role as home keepers to work in factories no matter how much advertising the government did. Those who did go to work battled to look after their families and work-related stress. 
So it can be said that the Nazi policies towards women were partly successful, since an increase in birth rate did occur, but it was these very policies which made women stay out of the factories when the war was on.
