I mean, realllly loves it! So much, she gazes at me and her eyes dilate when I'm singing it! Its awesome! Needless to say, I sing it to her pretty much everyday. Its especially cute because after the first time, she says, "Dada?" that means she wants me to sing, "Happy birthday dear Dadaaaa". Then, after that song she says, "MomMom?" So, I sing it to myself. This goes on for a few more people, then we're finished and moving on to something else.
