Emma and Andrew are slowly beginning to learn how to sing songs. Emma actually has a small repertoire of songs so we can probably drop her off at the 3rd Street Promenade next to that silver robot dude. Andrew is still 2-3 months behind Emma with his speech and language development, so he has a more difficult time stringing together words in order to sing a song. His version of singing is to shout out the first or last word of a verse. I call it Tourette's Singing.
Here is a short video of the kids singing the classic song Twinkle, Twinkle, Little Star.
