I finally became "Mom"

After 6 1/2 years of being "Mama" I have become....Mom. Mom! Chris has also become "Dad".  
Bub is suddenly so grown-up!  Once in awhile, he tries out Cynthia and Chris.  It's pretty hilarious.
The other two better call me Mama for the rest of their lives, though. I love the soft way Cubby says "Mama"  as he burries his face in my neck.  I feel like a Mama has cuddley babies but a Mom has surly teenagers.
There's no halting the inevitably of that transformation, mine or theirs.  We're growing and changing together.
I'm just grateful to have extended my Mama time by one more child.
