That's a great start!
Yes, very good start. My son could sing songs long before he could take words and make sentences. He could sing the entire Barney I love you song, yet couldn't (and still can't) just say I love you. It's coming, Mama. Hang in there.
Buffalo Soldier!! - the boys got taste! :) such a fun song.
I love hearing things like this because I am going through the same thing with my son.
That's so cool!
