When you spend most of your time with a 16 month old with a quite limited vocabulary who can only sing extremely small portions of a song, over & over & over & over & over--you can go somewhat crackers with that portion of the song. Right now her fav song is E-I-E-I-OOOOOOh! E-I-E-I-OOOOOOOOh!!
Much as I'd like to, I can't pick up an instrument & play a different tune since I just put the little Monkey down for a nap.
