I try to play it throughout the day (paci-less to hopefully get him to try and talk) and he gets so excited when we start it up. He knows to touch the screen when the animal knocks on the barn door.
Other than reading, pointing out objects, and playing this game I don't know what else to do to encourage him to try and talk. I have thought about getting rid of the paci, but he only has four eye teeth to cut and then he is done until the 2 year molars. I know he likes to have something to chew on when he cuts teeth so I just don't have the heart to take it away until those come through.
