Try this activity.  Name all the items in the top picture.  Have your child point to the one you name.  You can even ask, "which one says moo" or "which one do you drive".  Then name all the locations in the second picture.  You can ask, "who lives in the barn"? or "where does the cow live"? Have your child point to the picture to communicate with you as they are learning to use their words.  Remember that the more successful interactions they have with you, the more they will keep trying to communicate in more and more ways.
