After the marriage, the couple try to plan about their family. They try to postpone the pregnancy. Their idea is "Let us enjoy together for some more time without added responsibility. Let us be free". This policy may not be advisable sometimes. Couples live together a loving life for a short time. But after one or two years of married life, with same faces, same life routine, they get bored. All the time they had talked, argued; exchanged ideas, knowing well each other, what next. But, instead, within a year or two, if a little wonder comes before you, both of you will have your attention on the baby. All the time, there will be only one topic of the new comer. They will have no time to think of their own differences to discuss. This way, they will be sharing the company of the baby. They both will be committed to the family. They may even sacrifice their own comforts and priorities for the sake of the welfare of baby. Thus the family grows. The life goes on. This is how the imaan completes from half to full due to the struggle to maintain the family. The girl becomes wife, the wife becomes mother. The boy becomes husband and later father. The life cycle goes on.
The couples getting children earlier, may get their support in life earlier when they grow old. If you marry at the age of 25 years (male) you may get child child when you are 27 years. Your child will be 25 years when you reach 55 year nearing retirement. The next generation will take over you in time.
There are different hormones working in the bodies of men and women. 'Testosterone' are more in men in their early life and till middle age. This hormone will give masculine qualities like growing beard and moustaches, sexy feelings erection of penis, emission of semen etc. In women, the hormone 'estrogen' is more than men in their youth till middle age. This gives them feminine behaviour, delicacy, monthly periods, soft skin, growth of breasts, shrill voice. But when men and women cross their middle ages, 45 to 50 years the action of hormones reverse. The testosterone in men decreases and increases in women. The men become less aggressive, adjustable, unlike earlier demanding dictating. Their sex power decreases. Where as this hormone increases in women and estrogen reduces. There by they become more aggressive. They get into commanding position in the family. "I have tolerated enough all those day. Not any more" is the attitude of them. Their breasts relax. Their menstruation stops. They under go 'Menopause' period. They make command of the house. They have the majority support of their children. Husband retreats and takes back seat. She wins the battle. She has the daughter in law to command. Husband has no energy to interfere in the affairs of the family. This is how 'Saas Bahu' battle starts.
If the daughter in-law and the family members understand this situation, they may handle the affairs of family better. Bahu should not oppose any move of saas. Gradually she can explain her point and convince her. If she confronts, war will prevail.
