Where is my child?

I'm missing a child. I have an impostor living in my home...one that has eaten vegetables every night at dinner for the last four nights in a row...including begging for more cauliflower over and over and over last night until she ate it all....she looks like my child...she acts mostly like my child...but she is NOT my child...Here's a recent picture...

When will the real Stella return? The one who won't touch a vegetable to save her life, the one who never tried cauliflower before last night, the one who laughs in your face when you try to give her a new food because you think this time she might try it but she knows better....where is she? Anybody see her? I will offer a reward for her return, as long as she keeps eating veggies...
