From Mommy to Mom

I am not sure how it happened but something changed. In the past 6 months I have transitioned from "Mama" to "Mommy" and now it's "Mom". For some odd reason Violet has been calling me "mom" all day. Maybe it's because my mom was here last weekend and that is what I call her or maybe it's just that she is growing up. Whatever the cause, I am hoping that "mom" doesn't last too long and I am "mommy" again soon. I should also mention that Violet was calling "dad" from her bed this morning. "Dad is it time to wake up?" What is going on? We aren't old enough to be mom and dad.
