We are watching Trebellina late in the morning. Baby C is 14 and a half months old, and he has been watching this video for about 2 months. As you can see, he is rusty coming out of the gate, but he attempts to sing the note middle C. He announces "Next Note!" when Trebellina says it. Then he sings D. He gets excited and distracted because Mommy is acting silly by the video camera. He then attempts to sing the notes E and F. As you can see the video is very engaging for babies and teaches them about musical notes.
