I don't know when most kids start singing, but although he has enjoyed music and us singing since his earliest infancy, Zion has rarely made any effort to sing himself. But today he has sung "Johnny B. Goode" 3-4 times! Its especially cute when he strums his guitar while he does it.
And then, at bedtime tonight, Liel made her first attempt at singing! Her choice of song was "Train to Chicago" (by the band Drink Me). I'm not sure how mere words can capture the hilarity of a 2 year, holding her stuffed Ice Bat, swaying back and forth on her bed and singing, "Drunk on the train to Chicago, I feel alright....", so I'll just say that I had a hard time singing through my giggles and I'll try to get a video of it. You'll love it.
