That little story may deviate from your particular family experience but it describes all the manifestations of the Moon in a person's chart. The Moon represents your mother and how YOU mother or nurture others. What did she show you? The Moon represents food since that nurtures us physically. And because Mom examples to us what emotions are appropriate, your Moon is how you express your emotions. The earliest experiences that include your physical environment compelling the deepest parts of you to develop, even prior to any conscious memory of them are also represented by the Moon. These beliefs will affect your home NOW and what you need to nurture your self there. It indicates in what type of home you feel comfortable too. The Moon is your grandmother, aunts and other important female role models. You carry their legacy in your DNA. As your mother carried you, you carry her energetically and spiritually. This is deeply embedded in the psyche. It is so second nature that to separate ones' identity from that deep emotional self is impossible and an obscene gesture at our soul.
Usually aspects to the moon or its sign or position signify your mother's personality. Her energy is indicates how and what emotions feel familiar to you whether we like them or her or not, it is our essence of our primary being.
Now a few may ask what about being adopted or not knowing the mother? Your DNA makes your emotional template real, that is your physical nature. However that is indicated by your birth chart too. Your Moon and its position do not change in your chart regardless of who raised you, your environment and free will add a layer to your experience just like being raised by biological parents would. It's a funny thing, the adoptive mother or caretaker or female role model seems to correspond to the Moon in astonishing ways, just as a natural mother would. I think we attract people who match our energies and a child would attract someone who corresponds with them from the beginning.
In a birth chart the location of the Moon and what house it falls into plus any aspects to it will tell your personal story of emotional expression and mom, for good or bad. It represents your legacy of memories and potential opportunities.
