My baby niece was up awhile ago while we was watching miss usa, calling me mommy. My sis would glance up at me like she didn't like it lol. I know how she feels cause I felt the same way when my son was smaller and called her mama lol. But they don't know at 1. She was calling her brother mommy too when she was wanting him to play toys with her lol. It's just stuck in her head and she's trying to get your attention that's why she says it.
