Signing: The swing sign looks two legs on a swing going back and forth. On your weak hand, extend your middle and index finger. Hook your middle and index finger over the fingers on your weak hand. Then move your hands back and forth.
Usage: When you go to the playground, make the swing sign before you put your baby into the swing.
