Introduce your child to the toy and let him or her explore it - discovering the sounds and features. If necessary, assist in spinning the moon and stars ball to let him or her hear the full chiming effect.
Encourage lots of spinning, shaking and rolling plus any move from your baby to follow the ball.
Talk about the sounds you are hearing and praise any independent play.
Initiate reciprocal rolling games between you and your baby - exaggerating praise and applause for any small achievement made
