Just a quick note. My son sang his first song yesterday. He was babbling like he usually does. But then we paid attention. He was only say “do do do.” but he definitely sang “Twinkle Twinkle Little Star.” He got the right number of beats, his timing was right, and he even gave mostly the right pitch to the notes. This is pretty exciting as I have some musical talent. It’s nice to know my genes contributed something to the mix.
