Two big girls?

The other night when I tucked Little Sis into her crib, she had me tuck in her baby. To be silly, I said, "Goodnight Baby Michael. Goodnight Baby [Little Sister]."

Even though she was laying with her head on the pillow, I saw her shake her head.

She may have even rolled her eyes.

And she said, "I'm not a baby, Momma."

No, my precious one, you're not. And tonight, you will spend your first night in a big girl bed.

How did this happen?!
