Sometimes my son really reminds me of how I was when I was a wee one. Ever since he started pre-school this year, he has been learning things like crazy. You can really tell that he is absorbing all the information that he picks up at school. The funniest part? While he sits on the floor playing with his cars or action figures, he always starts singing or humming. He learned a bunch of songs from school, but his favorite is The Excavator Song. The Excavator Song He knows the whole song by heart and sings it nonstop.
