You may want to leaf through the book together, and look at the special illustrations. Perhaps you could ask your child to notice the different perspectives and angles from which the illustrator chose to draw Mooha and Booha: up close and from afar, from down below or high above, from the front and back. You may enjoy picking an object at home, and trying to draw or photograph it from various angles.
How about acting the story out together using puppets? You could suggest that your child try to convince the cows to stop bickering, and enjoy their grass.
It is often difficult to admit that we are jealous of others. Perhaps you could share an incident with your child in which you were jealous of someone else when you were growing up, and how you coped with that feeling.
Mooha and Booha cannot enjoy their own grass, because they focus solely on what the other has. You may want to toss a ball between you, and have each of you say something good that makes them happy as you take turns catching the ball.
Seasons change, the green grass turns yellow, and the cows cannot stop fighting. Perhaps you could make a “grass head” using old stockings, some soil, and grass seeds. Take care of the grass head together, and discover how long it takes for the grass to grow at its top.
You can ask your toddlers – do you like tickling games? Which of the games that we play together do you enjoy? What would you have liked us to play? In relation to the mother’s telephone call in this book, you can also ask – how did Gan-Yah feel when her mother went to answer her phone? How do you feel when you have to wait?
Walking in the dark: Pat can find his way in the dark. Can you? You may want to turn off all the lights, and walk from one room to the other holding hands. Feel your way around, and rely on your knowledge of your surroundings. After several times, you could allow your child to lead you.
