My big girl/my baby girl

How can one person be all of that? Today I saw both in Lauren. She is so big and independent minded, and then, she cries for "Momma!" I took her to a daycare for a trial day, actually just for a trial few minutes. She was fine until two little boys screamed in her face. After they were scolded, they came over to apologize and she screamed, "NO! NO! NO!" Guess she learns quickly to stand up for herself...
I still see my baby when I see her, but her big girl side is starting to show. Damnit...
