Signing: The sign for telephone looks like you are talking on an imaginary telephone. The telephone sign is made by extending your thumb and pinkie, holding them to your ear and mouth respectively.
Usage: Guard your cellphone, because babies love to imitate and if you speak on your phone, your baby will want to as well. Make a game out of it by asking your baby to make the sign for telephone.
