Imitating Melodies

As I type I'm listening to our almost two year old hum and babble the tune of the ABCs.  I guess it could also be Twinkle Twinkle or Ba Ba Blacksheep but I actually don't sing those two with her much. She does however, love to push the ABC song button on our Leap Frog Fridge Phonics game on the refrigerator. I remember being surprised to hear children at this age sing melodies.  Some of the children who played with Zachary when they were this age would sing like this. I don't remember Zachary singing melodies that clearly at this age.  I love how they are all different! I guess Adelyn is trying to perfect this song because she  sings it quite frequently throughout the day.  She loves the piano also.  Can't wait until she is interested in lessons!
