Jonah learns the hard way that he should go God's way when he is swallowed by a huge fish.
Whose way is perfect? God's way is perfect.
"God's way is perfect."
2 Samuel 22:31, NIrV
As you drive or take a walk, tell your child which way you need to go in order to get where you're going. Ask your child what would happen if you went the wrong way. (You would not get where you need to go.) Talk about how God's way is perfect. That means God's way is never ever wrong. God's way will always be the best way and will get us where God wants us to go.
