Juliet is constantly "singing" her little heart out. It's clearly more of a hum than anything, but she definitely hums to the tune of whatever song she is "singing"! I have been trying to get her to do it on video for awhile, but she apparently has stage fright and refuses to do it on demand. The first time I heard her hum this was actually February, which I have to say I was pretty impressed with!
Anyway, I was shocked when she appeased me this morning. I decided to go for the bonus and ended up getting her version of "Swiper, no swiping!" at the same time =)
