C: Momma, why your name is Momma?
Me: Well, a woman has her own name, like Pamela. But when she has a child, then her child calls her Momma, and that becomes like a new name.
C: Or Mommy, or Mom.
Me: Yes! She can be called Momma, or Mommy, or Mom. Or Mother. But Momma, Mommy, and Mom are sweeter and nicer.
C: Oh...Okay, Mother.
