Song is signed exactly like music: take your non-dominant forearm and hold it across your body. Then, take your open dominant hand and wave it back and forth above your other flat hand, as if conducting an orchestra.
Time to play some baby songs and do some baby dancing. Make the song sign before you switch on the music, and soon your baby will figure out how to tell you when they want you to start playing some tunes!
Signs like song are better demonstrated rather than using the flash cards. Turn on the radio or crank up some iTunes to help your baby learn the sign for song.
