"Volume up, volume up, volume up."
Alec used to always love to let out a scream, which was a cute squeaky chirp of a scream, but sometimes he would try to scream and all that came out was a sqeak. He would get upset and say, "My scream is broke" and whine a little. Then he would put his fingers at the corner of his mouth and turn them like he was turning a dial and he would say, "Volume up, volume up, volume up." Then he would try his scream again and if it didn't sound right then he would repeat this process. He did this until his scream sounded just right to him. He was picky about his scream. And it was the cutest.
When Cassidy's scream broke, it sounded just like Alec, and she worked on her scream til it came back.
