Kids are so funny. We were looking through some of our old family videos, and we found this clip of my daughter singing. My son was copying her and she was getting so mad. She's 2 and he's almost 5. Here's the YouTube video. Click on the arrow to see my daughter singing Twinkle, Twinkle, Little Star.
