She sings in the car. She sings in the bathtub. She sings while she wanders around the house. I think I've even heard her singing in her sleep. Sometimes you can recognize the tune, like the ABCs, the Wheels On The Bus, or Row Row Row Your Boat. A lot of times it's a completely made up song with words like, "I love daddy. I love Brenden." She even does hand motions now.
This isn't the best video, but you can hear her mixing a few songs together and laughing at herself. She absolutely loves singing, and we love listening to her.
