Ba, Where are you?

I told Sophie this morning she can't take Pato (duck) to school (Pato is irreplaceable because she sleeps with him at night so he isn't allowed to leave the house). I told her to go find Ba (Oveja, which is sheep in Spanish. Oveja has been shorted to Ba) and bring him instead. She walked into her room and using perfect sing-song intonation, she said, "Ba, where are you?" Wow, she used a question word, subject-verb agreement and rising intonation all at once. Bravo, Sophie
