I think with both of my kids my favorite thing is when they start to sing. This is Harper singing "Popcorn Popping on the Apricot Tree" from school. This song is a standard for Utah kids. Helena and Harper both know it, although Harper has the words a little off. I enjoy his improvising. :)
(Real Lyrics):
I looked out the window, and what did I see?
Popcorn popping on the apricot tree!
Spring had brought me such a nice surprise,
Blossoms popping right before my eyes.
I could take an armful and make a treat,
A popcorn ball that would smell so sweet.
It wasn’t really so, but it seemed to be
Popcorn popping on the apricot tree.
