How is your mom your mom?

Answer 1

Your mother can be your mother in many ways:

• She is your biological mother; she bore you and birthed you.
• She legally adopted you; another woman bore and birthed you.
• She married a man with children, so you are her step-child.
• A surrogate woman bore and birthed you, then your parents adopted you.
• A family friend or someone raises you, but never adopted you, but you came to call that woman "mother".
