Kali 2.4 is quickly becoming quite the singer. She knows a lot of songs from her favorite movies. It's not uncommon to have her break out singing regularly. She has the usual Disney favorites along with movies like Annie or some Sesame Street shows that she enjoys.
The other night, we watched 'The Sound of Music' for her first time. She was zoned in on the movie the whole time. Songs come pretty regularly and the kids in the movie keep the action interesting for her.
Later that evening out of nowhere, she suddenly exclaimed, "The hills have sound of music!"
Granted, it wasn't the exact line ("The hills are alive with the sound of music!"), but it definitely caught me off-guard. She had only seen it once, but she had already pick up on one of the main lyrics. Pretty impressive.
