We have a Hummer..

Her name is Alexa! For some unknown reason she hummed all day today. She hummed along to songs on her disney shows, and some commercials she knew, but mostly just hummed random tunes. No rhyme or reason. And not occasionally, all day.. no matter what she was doing. The only time she stopped was when she took a nap and when she fell alseep at bedtime tonight. I am curious to see if she continues to hum tomorrow! (Tristan even put his finger to his lips a couple times and told her Shhh!)
