Twinkle, Twinkle Little Star

So my Kruzie is just a few days shy of 20 months now and getting so big. He doesn't say many words yet, but here are the standard ones. "Mama", "dad", "up, up, up",(he says that alot). For a long time now he has said "thank you", but he has always said it like it would sound if we did it with our lips together. Try it...that's what it sounds like and he definitilty knows what it means. He has just recently picked up the "u u" while shaking his head no. I guess it'ss better than hearing that dreaded "no." He doesn't really say much more than that, but he's getting there.
Well a week or so ago, I heard him doing something and I thought "No, it couldn't be." Ever since he was a tiny baby, the girls have loved to sing to him. The first song they would sing was Twinkle, Twinkle Little Star. Wherever we were and he was crying, they would sing this over and over and over again. Usually it's in the car, the stroller, wherever, but they still sing it, even now when he's 20 months. Well I heard him the other day humming, Twinkle, Twinkle Little Star. I doubted it at first, but Kylee said "Mom, Kruz is singing Twinkle, Twinkle Little Star." I knew she was right. Well today we were in the car and Kruz was sing "Ma Ma, Ma Ma Ma Ma Ma.... YES Twinkle Twinkle Little Star. Kobi heard it immediately. I wish so bad I had my camera to record it. That is my goal over the next couple of days, to get that on tape. It is just aborable and I want to have it forever. So my son might not talk yet, but he sure can sing!!!
