This is true not only for humans but all mothers of the animal kingdom. A tigress will attack you and kill you if you dare to approach her cubs. Every animal mother teaches her young ones the art of living in their world. Every mother is ready to go to any length to save her young ones. A woman begins dreaming about her child soon after conception. Many expectant mothers talk to the yet to be born child. They feel totally comfortable doing that. They plan for the future of the kid, food, education, clothing, shelter everything. From the poorest to the richest mothers, we find that a sense of protecting her progeny is the most common trait.
For a mother, the child is her extension. This is not so for the fathers. But mothers treat the child as same as themselves. Why? Nature gives this love to a mother so that the specie continues. Mothers are special. In few studies it has been found that infants stop crying when they listen to the recorded sounds of their mothers womb. They were protected there and when they come out in the world, they are surprised with the difference. The sounds of womb tell them that things have still not changed so much and they feel comforted. That is one of the reasons why touch works wonders. The more a mother touches her children physically, the more loved they feel. They get the reassurance of the protection of the mother.
A child should always feel indebted to his/her mother because nobody else including the father sacrifices so much as the mother to bring us up. Mother is compassion and for a young kid, mother is God.
