"Mom"

Callia started calling me "Mom" today. Up until this point she has always called me "Mama", "Mother" (which I think she got from Bambi), or "Mommy", respectively. She must have called me "Mom" 20 times, inserting it wherever she could, and she was obviously really thinking about it and feeling grown up. It made me feel like its the end of an era. I have been noticing lately that she has been changing a lot.
