Harper's ABC's

I have no idea when most kids start to sing and know their ABC's, but Harper's got the song down pat and he knows almost all of his letters as well. He has a Leapfrog magnetic alphabet set that hangs in our kitchen and he plays with it quite often. When you push one of the buttons it sings the alphabet, and boy has he pushed that button a few zillion times. :) It's been just recent that he will burst into song while playing, and I absolutely love it!
