Chase attempting to sing

Chase has been singing more lately, and can sing Pat-a-cake, Popcorn Popping, Twinkle Twinkle, part of Happy Birthday, and probably a few more. I catch him singing sometimes by himself, but as soon as he sees me it typically stops. Anyway, he was willing to sing for the camera today, but as soon as I bring it out he starts acting goofy and mumbling all of his words. So this isn't the best example of him singing, but I thought I would put it on here for my mom to hear him sing "Happy Birthday" to her since it is our birthday tomorrow. Happy Birthday, Mom, even though you will probably never come on here to see this :). I love you so much, and thanks for giving birth to me on your birthday 26 years ago.
