Jude singing

Jude and I spent the day at Vo's to celebrate Terra and i's birthday. Jude was very interested and loving toward baby Calvin today! Jude set up toys in front of his face to keep him happy, and repeatedly sang "Twinkle Twinkle Little Star" to baby! Jude told me " to make the baby happy , you need to "higher" your voice", and then sang to his cousin in a high pitched voice.
