"Mic-phone"

You know what I love about staying home with Caleb?
Our dance parties. Caleb loves to sing into his microphone. Every time I sing he starts saying, "mic-phone, mic-phone mommy!" Once he's found it in his mound of toys on the floor we can continue our singing.
Today, at 10:00 and still in our pajamas, we put on some good ol' Backstreet Boys danced our little hearts out and sang at the top of our lungs, "I want it that way!". When I sing I must make some odd faces becuase whenever Caleb is pretending to mouth words into the microphone he has a grimace on his face. Where would he learn that?
