Becoming Mama

The Ant Bug has recently started calling me Mama. I used to be called Mommy or Mom. For awhile she repeatedly inquired "what does Daddy call you?" until she learned my real name. But now she calls me Mama. Is it because we live in the south? I'm not sure what prompted the shift. But I like it.

"Watch this, Mama!"
"Mama, will you help me with my shoes?"
"I love you, Mama."
