I expected motherhood to cause some profound changes in me.

For some reason, I thought the simple act of giving birth would transform me somehow into a woman that was deeper, wiser, and more complex than the girl who walked in to the hospital. I expected to radiate some magical "mother" vibe to all who saw me.

Surprise! I am still the same person as before, with the same likes and dislikes, the same stupid insecurities and goofy quirks. The only real change has been my capacity to love; it has literally grown to proportions I can't try to describe.

For the most part, I walk around feeling the same as I ever did, but there are unexpected moments when the fact that I'm a mommy hits me like a ton of bricks. I've had several of those this weekend, so I thought I would share a few and hope you'll add your own...

You know you're a Mommy when...

...your young co-worker is excitedly telling you about her plans to camp out for an iPhone, and your only reaction is, "Do you have sunscreen?"

...your potty-training daughter has a MAJOR accident, and you don't even blink while cleaning a seeming avalanche of poop off the floor, her legs, your shins, and the bathroom counter (how did it get THERE?)

...instead of singing Gwen Stefani songs in the shower, you find yourself humming a tune by the Backyardigans.

How about you ladies? When are you unexpectedly reminded of the fact that you're a mom?
